About to fulfill a dream I've had for years and don't quite know where to start. About 3 friends will be setting out on a lifelong dream trip to S.Africa. Not quite sure where to begin planning. Naturally we'd like to see a safari or 2, Kruger NP is definitely on the list. However, wasn't quite sure if we should be seeing other places in S. Africa besides Cape Town. Is there much in Jo'burg, Durban etc? Definitely would like to do some of the wineries and also the gardens. Is it worth a trip to visit Botswana or Namibia, I've heard a lot about these 2 countries. We have about 2 and a half weeks total, and hope to fly out of NYC or Washington DC. Many thanks in advance.
