Sorry, why would you only do one camp?? If you're going to go to Africa, do it right. Going to different camps really gives you the ability to see different animals, different terrain, etc. If you're going to make the effort, make it a trip worth making..

If I were going to answer your question straight up with only ONE camp, it would be Mombo.... Mombo, for me, has the BEST combination of spectacular setting, spectacular food, out of this world service, and the BEST animal viewing in Botswana. That said, in general, you could probably spend about two to three times as long in the bush, if you go to other camps.
