We went with Overseas Adventure Travel (OAT) in April 2022, to southern Africa. Our itinerary was a bit different from their current Ultimate Africa safari, but similar. Camps were comfortable, verging on luxurious in a couple of places, and safe. The price and value were hard to beat.
A major factor with OAT is small group sizes - max of 16. They also offer pre- and post-trip add-ons. We signed up for the Botswana Okavango Delta pre-trip (Botswana was THE best for wildlife viewing), and as no one else did, we got a private tour for 5 days. While OAT offered a post-trip to Cape Town, South Africa, we did that on own (it’s a city, after all) with a private guide. It was cheaper than the OAT post-trip extension, we were back on our own after weeks with a (admittedly small) group, and we also toured the Garden Route with a rental car, which the OAT portion didn’t offer.
If you go to Cape Town without a group, stay at the Parker House B&B, and hire Chris Hannival (Hannival Tours) as a private guide.
We’re leaving in a week for a Vietnam tour with OAT, not going on their pre-trip (no one in our announced group is, apparently), and doing our own, longer post-trip to Cambodia, rather than OAT’s. The main trips are real deals, though, and always include educational sessions and opportunities to meet and have meals with locals.
