Thanks to everyone who has responded!

We have yet to finalize our lodgings in Cape Town. I suppose I should have mentioned we are on somewhat of a budget as I am a graduate student and my wife recently graduated. Here is our current (tentative) itinerary:

Arrive the night of Mar 2, stay in Cape Town.

Mar 3-5 tour Cape Town, including Robben Island, Table Mountain, and others. We are renting a car upon arrival Mar 2.

Mar 6 stay the night in Simonstown.

Mar 7 tour a couple wineries, stay in Stellenbosch.

We're not sure when we'll make it back to South Africa, so we wanted to see Kruger even though it will cost us some time (due to additional travel) and money.

Mar 8 Fly out of CPT into JNB at 615, arrive at 815. We are booking this on the SAA website for 1000 ZAR each (roughly $130). It looks like it is a 40 minute drive from Stellenbosch to CPT. How early do we need to arrive at CPT?

Upon arriving in JNB, rent a car and drive to Naledi Bushcamp (approximately 5.5 hours). Hopefully get there in time for the evening game drive.

Mar 8-11 stay at Naledi Bushcamp.

Mar 11 after morning game drive, return to JNB for flight at 7:40 pm (JNB-FRA-IAD).

Any comments on this itinerary are greatly appreciated!
