What Makes Overseas Adventure Travel Stand Out?

Touring southeast asia with Overseas Adventure Travel (O.A.T. Tours)

Overseas Adventure Travel is solo traveler friendly. They offer free or low single supplements. OAT understands that solo travelers desire to follow their own schedule, desires and needs. They help handle all the details to make sure your trip is affordable, easy and enjoyable.

A major focus of OAT is cultural immersion. Travelers can expect to visit local schools, churches, and homes (where you might be treated to a home-cooked meal). Experienced guides — all fluent in English — lead groups off the beaten path when possible.

OAT strives to give back to the world they send travelers around. A portion of all proceeds goes to the Grand Circle Foundation, which supports cultural and educational programs in the countries visited.

Who Will Enjoy Traveling With Overseas Adventure Travel?

  • Ages 50+

OAT specializes in small group tours around the world serving Americans aged 50 and older. They appeal to the old fashioned – the fact that they still offer a physical catalogue is testament – and their travel style reflects an appreciation of the classics coupled with an adventurous spirit to explore each destination deeper and from a local perspective.

Overall, prices fall into the moderate range, and are especially a bargain for solo travelers, who can save substantially by not having to pay for single supplements. Accommodations are designed to be both comfortable as well as unique and in keeping with the local spirit of the destination. If your hostelling days are over but you feel too adventurous for a standard hotel, OAT will be a great company to travel with.

OAT travelers are those with a passion for culture. They don’t just want to see a destination, they want to experience it. For these travelers, spending a day in a Maasai village in Kenya, eating dinner with a local family in Chile’s oasis town and interacting with local musicians at the bustling Libertad Plaza in San Salvador, Belize is a welcomed adventure.

Top Destinations

OAT operates tours all over the world, specializing in remote, off the beaten path destinations. African safaris are an especially popular offering, though you can also travel to Japan, India, Peru, Iceland, Vietnam, Albania, or Morocco, to name just a few of its far-flung destinations. OAT also runs small-ship cruises through the Galapagos, on the Amazon, and along the Turkish coast.

OAT Travel Style

With Overseas Adventure Travel you’ll find a combination of transportation and accommodation styles, but all with an element of comfort. Groups are small, with a max of 16 (24 on small ship cruises).

Accommodations vary, but generally favor being local and non-traditional over a basic centrally located hotel. Their exact words are “emphasis on authenticity, rather than amenities”.

Their style is all about unique and meaningful cultural interaction. While you’ll learn the history and see the famous sights, their true focus is about people and connections. This means you’ll enjoy meals with local families, like you’re just a friend over for dinner; visit schools and see the amazing work being done in small communities. The visceral understanding and perspective that comes from learning to cook traditional meals and make traditional crafts is what you’ll find on an OAT tour.

Why Choose a Tour with OAT?

OAT offers a unique up close and personal experience, guaranteeing that its groups will never exceed more than 10-16 travelers. A spirit of spontaneity is part of what makes traveling with OAT special, as they strive to take advantage of every interesting opportunity during a trip.

Traveling with Overseas Adventure Travel allows for an in depth cultural travel experience in comfort. Many opportunities exist for travelers to find deals, and it’s a great way to meet new friends in a similar age range.

If you traveled extensively in your youth and are not ready to slow down, but perhaps are looking for a few more logistical ducks to be taken care of for you, OAT could be the perfect fit. They offer a variety of options for more independent minded travelers, as well as ample free time to explore and plan your own adventure during cruise port stops and on their group tours.

Alternatively, if this is your first travel experience, OAT will be a great starting point. You’ll gain cultural insights, meet locals, as well as hit on all the best tourist sites that provide cultural and historical context to your destination.

Overseas Adventure Travel Reviews

I’ve taken 2 tours with OAT. They do a great job of handling all the arrangements, and I’ve had an excellent experience talking with their customer service representatives. Their tour leaders and guides have been consistently knowledgeable. And I love that there is no single supplement.

Date of experience : August 05, 2022

Our 2022 Transparency Report has landed

4 Phone Calls, 8 hours 23 Minutes On Hold

Customer service, has OAT even heard of this concept?

The cover letter that came with my final documents has NO CONTACT information for OAT just in case a customer needs to reach out. No email. No phone number. This SCREAMS: “We have your money, and we don’t care to service your needs.”

I had to resort to the numbers available on the website. Here’s my call log:
• June 7, 2022: called 800-221-0814 at 1:05 pm, on hold for 3 hours 16 minutes. An automated message told me I had reached the maximum hold time, was being disconnected, and someone would call me within 72 hours (NO ONE EVER CALLED ME BACK!).
• June 8, 2022: called 800-221-0814 at 9:03 am, on hold for 2 hours 14 minutes. Could no longer stay on hold, as I had to attend a meeting.
• June 10, 2022: called 800-955-1925 at 9:01 am, on hold for 2 hours 8 minutes. Could no longer stay on hold, as I had to attend a meeting.
• June 11, 2022: called 800-221-0814 at 9:01 am, on hold for 1 hour 5 minutes. Despite having followed the prompts for needing to speak with someone about the airline reservation portion and departing within the next 4 months, still got transferred from one agent to another and put on hold yet again.

I also tried sending an email. The automated response was that someone would respond within 15 business days. Really, 3 weeks to respond to an email?

Would Alan & Harriett Lewis, the owners of OAT, have persevered if they were customers? Called 4 times and stayed on hold for a total of 8 hours 43 minutes? ONLY TO BE TOLD THAT BECAUSE IT WAS NOW SO CLOSE TO THE DEPARTURE DATE, CHANGES WOULD NOW BE AN ADDITIONAL $$$. All of my time and effort were futile.

Back on August 14, 2017 OAT posted an apology for poor service and long hold times on their website titled “We Owe You an Apology – Addressing our service issues.” Yet, once again, OAT has the exact same problem. Why didn’t OAT learn the value of that lesson the first time? Shameful for a service business to not prioritize its customers. And this didn’t just happen, it’s been going on for months (just look at the reviews posted on TripAdvisor).

OAT is in serious need of a customer service make-over, starting with the website as well as competent staffing. There is no chat feature on their website, nor the ability to send an intranet email. Customers traveling within the next 30 days are not provided higher priority than someone traveling 4 months from now. It is obvious their needs are more immediate. This isn’t rocket science. For heaven’s sake, OAT needs to step in to and up to today’s technology expectations for a multimillion-dollar travel company.

Believe me, an apology will not repay me for my effort, frustration, disappointment, and time spent apparently uselessly trying to reach OAT. Results count, excuses do not.

I am stuck traveling with a company that does not have the capability of helping its customers.

Overseas Adventure Travel
reviews & complaints

I had booked and paid in full three attempts for a Kenya and Tanzania Safari. OAT cancelled all three. I was added on to a fourth booking two months before departure. However, I lost the reasonable airfare paid for in November 2021. Now I had to pay another $5,000 for the new airfare, increased cost of insurance and an extra hotel room after my group left. I was told in June that I would get a $1,000 refund in 2-3 weeks. That never happened. I have called OAT several times and was told that there would be no refund. OAT is the reason that I had to pay more, not me.

I am a 14 time traveler with GCT/OAT and will not travel with them again. I am on hold right now for 30 minutes waiting to tell an agent to take me off the mailing list! I get daily emails from them. I am done with OAT

Desired outcome: I expect a partial refund and a response.

Overseas Adventure Travel – Refund for canceled trip

On June 9, OAT (Overseas Adventure Travel) canceled my paid June 12 trip to Mongolia/South Korea. They asked if I wanted to reschedule, and I declined.

On July 1, OAT emailed me and canceled a post-trip for my scheduled October 1 trip to the Baltic. I phoned and told them that I would still take the trip and that they could take some of the $7,340 that I paid for the canceled Mongolia/South Korea trip and refund the rest to me. I stated that I asked for this refund on June 9 when they called to cancel the trip. I was told by the travel consultant that they were processing the refund but it takes 2 weeks. It was more than 2 weeks so the consultant said he would resubmit the refund request. I phoned on 7/21 and was told that a $2,719 refund request was sent to process on 7/14 and it could take a month. Since the money I owed on the Baltic Trip was $2, 916, where was the rest of my $7,340? My math makes $7,340 less $2,916 is $4,424. He said he would take care of it. Yesterday I received a late notice for payment of my Oct. 1 Baltic Trip. It states I owe $2,416. I phoned today and spoke to Jeffrey who told me that the bill was sent by a separate department and that my refund will now take 45 days. HELP.

Desired outcome: A refund check for $4,934. That is $7,340 (paid to OAT on 4/12/22) minus $2,416 (due for Oct.1 trip per invoice #07 4/24/22) for a total refund of $4,4934.

Overseas Adventure Travel – Immediate return of our money.

Unfortunately, this issue continues from BBB-Boston claim #[protected] which I thought was to be resolved. Concerns a trip to Turkey that Overseas Adventure Travel scheduled for April, 2022. OAT canceled the trip. We had paid in advance the amount of $8009.00. After we filed with BBB OAT said they would refund our money however they said it was given as a voucher and would take 30 days to send to us. That was in early April. When I emailed them last week they said it would an additional 45 business days. I have trust issues now with them. I fear that they are not going to return our money.

Overseas Adventure Travel – Trying to contact OAT via phone calls

We have to cancel our trip to Australia and have been trying unsuccessfully to contact OAT via phone calls. We have been trying for over 1 week with no results. always on a wait list, “we will call you back within 24 hours” message after waiting for over 3 hours. and no call back.

Overseas Adventure Travel – Impossible to reach by phone or any other way

We had one great trip to Columbia 2 years ago, then booked a trip to the Baltics & Russia scheduled for 2020, then it was canceled rolled over to 2021 due to COVID, then it was canceled rolled over a 2nd time to 2022 due to COVID, then it was canceled a 3rd time for 2022 due to the invasion of Ukraine. Calling to get a refund or credits is impossible. For four days in a row times we were on the phone for 3 hours and never got through. When we finally got through, the customer service person was not well informed. We were offered a partial refund with the rest as credits, but when we saw the refund in our online account it was short by $600. We called to ask about it but waited on hold for 5 hours – and never got through. We were also told we’d get a call back with a day/time specified, never got the call. We sent emails to their customer support email address, never got a reply.

We have been trying on a daily basis (when the Boston office is open) to clarify our airfare, adjusted airfare (post-trip was cancelled by OAT but WE must pay for the rebooking?), and errors on our flights to Italy. We leave in less than two weeks. This is our 19th trip, and we had always been satisfied with the Boston office’s responses. After 3 hours and 15 minutes on hold, our calls are disconnected with a promise to return our call in 24 hours. Guess the company is short-staffed and filled with newbies who won’t understand customer service.

Overseas Adventure Travel – Refund for cancelled trip Reservation No 3961333

The trip was cancelled September 30, 2021. I have been sending more than 50 (FIFTY) emails because they failed to fully refund me. They issued a check for me which I never received and asked them to immediately cancel it. This is easily done by accountants. Again weeks passed and I was patient because apparently they are afraid I could cash their check. I had enough patience though.

I asked to refund me on the credit card originally used as they did with the biggest part of the money. Nothing happens. They only reply withe usual THANK YOU FOR CONTACTING OAT and IT WILL TAKE A FEW DAYS.

Desired outcome: Moneynrefund

Overseas Adventure Travel – Failed to honor incentives to reschedule and added cost of airfare on a trip with free airfare

A trip to Egypt was originally scheduled for 04/20 but cancelled due to the pandemic. International airfare was included in the cost. The original reservation was #3910108 and changed to 3975236 when I rescheduled. I received a letter dated March 21, 2020 from the CEO, Harriet Lewis stating that I could get a full refund, reschedule for later 2020 or in.

Overseas Adventure Travel – Getting a refund due to Covid cancellations

Desired outcome: Full refund for trip plus insurance

Overseas Adventure Travel – Travel cost for reservation

I would like to complain on a recent reservation. We made our reservations number 395357 for myself and Friend on early February. We told the travel agent we were flexible and wanted the best deal. We booked a departure date of November 5, 2020. The travel agent never told us that a $500 airfare was being offered if you depart in Sept or October. If we knew.

Overseas Adventure Travel – simply horrible

They provide a strange kind of service. I booked from them for the first time recently and had some questions regarding my trip. Couldn’t reach them through their website forms and emails. Decided to call and was on hold for about 40 minutes without somebody picked up the phone. I just stopped calling. I understood I was just wasting my time. This is terrible what you do.

Overseas Adventure Travel – Mexico – oaxaca & merida

I booked first time through OAT for Mexico, specifically for a 1st-time tour with them because they prominently display their trips are 10-16 maximum guaranteed. –OAT opened an account in my name, which shows my booking with OAT to this day. However, the trip is led by the OAT-parent company Grand Circle. Nowhere on the Grand Circle website does it inform.

Overseas Adventure Travel – Don’t use them

This past month (November 2010), my mother treated my husband and I to a 3-week African safari. She booked the $25, 000 trip through Overseas Adventure Travel, a subsidiary of Grand Circle Travel LLC. The trip included international airfare for each of us, however, since she lives in a different U.S. state than we, OAT booked her onto a different flight than us. Since our trips were all booked and paid for at the same time as travelers on the same trip, I thought it was extremely cheap for OAT to put my 78-year-old mother on an international flight all alone. They obviously did it because the cost was less. Then to make matters worse, the layover in London for my mother’s flight from the United States was only 1 hour. Nowadays with the additional security checkpoints, it is absolutely impossible for anyone to make a connecting flight for international travel in 1 hour. So, as you would imagine, my mother did not make the connecting flight to Nairobi. The next flight out of London was 7 hours later, so my mother sat in the Heathrow Airport by herself for 7 hours, and by the time she arrived in Nairobi the next morning to begin our safari tour (which was leaving Nairobi at 9am), she was exhausted. Would you want your 78-year-old mother to begin an expensive excursion halfway across the world in a physical state like this? My husband and I were really upset about it. Upon her return to the United States, my mother called OAT to complain about their huge error in booking her outbound flights. To truly show their indifference to the magnitude of the situation and their obvious lack of professional customer service, Overseas Adventure Travel responded to my mother by telling her that there was nothing they could do for her since that was the only airline flight available at that time. You and I know that is totally bullshi_. If it were true, ALL of the U.S. travelers on our trip would have been on the same flight that she was on – but we weren’t. I’m appalled at OAT for taking this stand, especially since the majority of their tour clients are over the age of 60. Do yourself a huge favor when booking your travel plans to foreign and exotic locations: do not use Overseas Adventure Travel / Grand Circle. You’d be better off spending your hard-earned money with a tour company who is much more attentive to your travelling comfort and safety needs.
