2 weeks time and no experience how and exactly where in Africa

Hi there - do you have any recommendation for us?
Travel time is end of March. We are seeking for a not stressful but very interesting trip - maybe would be better to have a domestic flight rather than a car? Botswana could be as well an option.... the idea is to have as well 1 week on seychelles or s.th. like this after 2 weeks Africa (we have in total 3 weeks). You see, we need definitely help :-) - THANKS A LOT for every recommenation/idea!!!
