Have been to Botswana 5 times. The Delta is spectacular - Botswana manages its eco-tourism by severely restricting the number of guest beds within large reserves. One very seldom sees more than one other vehicle on a sighting - in Kenya, there might be 20. All of the camps in Botswana are permanant tented camps, but it is far from roughing it. The tents at Mombo are 40 feet long, hot and cold running water, indoor and outdoor showers, King beds and a private Sala where you can nap outside. Clearly, the SA lodges are more luxurious - my experience is limted to Singita, Mala Mala and ulusaba, but there are tradeoffs with respect to the wildlife experience, in my opinion.
