Wasn't planning on returning to southern Africa but there was this killer sale on Emirates to JNB from Seattle so I was forced too

Have reservations already for KTP,now want to go back to Botswana
Really do not feel comfortable doing a self drive there like we do in KTP and KNP so am going with a local company and doing a more cost effective option than flying in and out of private concessions.Will be doing a Mobile safari ,camping in tents ,but with a guide,so it's not cheap and want to get value for my dollar
Planned stops are Moremi,Savuti and Ihaha with 4 nights in the delta staying at BOGA campsites
So,what's the deal? how crowded does it get in the public areas of the park? Will there be a dozen vehicles at a sighting? I was assured the BOGA campsites are very private;the last thing I want to hear is noise beyond the sound of animals
I did look over a few posts here and it's looks OK just want to be reassured
I know you guys will come through for me!
