First time safari visitor interested in feedback on best areas for big cat (cheetahs, lions, and leopards) viewing in late Aug/early Sept? Also interested in elephants, giraffes, rhinos, hippos, etc. but big cats are the priority. Victoria Falls looks interesting also but only after our wildlife viewing has been fulfilled. We'll be in Cape Town before so travel convenience is also a factor. Looking at a 3-7 day follow on to Cape Town.
