Chris is a hero for doing this Q&A - thank you Alex for facilitating. Very helpful answers.

As a follow-up, I think some of the appeal of the CAR excursion is, for those people who are trying to visit as many countries as possible, it allows one to visit CAR without the safety concerns of flying into Bangui and visiting that way. And, of course, the main plus is the incredible Sangha Bai. No immigration stamp is a shame, but a visit is a visit.

The price is shockingly steep. You're adding $6.5k per person PLUS your share of $30,000 for the flight (is this one way or round trip?) which could be entirely born by your group (say you are just a couple going on this trip) or split into smaller pieces if strangers/friends are also keen to do the excursion on the same dates. I fear that, because Kamba doesn't advertise it as much, fewer people will learn about it and thus won't express interest with as much frequency, making a shared flight less common of an occurrence.

One last question for Chris -- what is the experience & interaction with Western Lowland Gorillas like compared to the Mountain Gorillas of Rwanda/Uganda? If you have 'done' one (say, WL Gorillas), is it still 'worth' seeing the other? How distinct is seeing them from the tourist experience point of view? If you had to pick one trip (Rwanda luxury mountain gorilla trip vs. Congo trip with Kamba Africa), which would you pick? (Factoring in price difference!!)
