Unfortunately I'm locked into April due to the schedules of some of the folks I'm traveling with. I can deal with colder weather, even if it's not preferred.
Will probably fly in/out of Joburg. I know we want to see Mandela's cell (is it worth it?), so that'll mean a trip to Cape Town, and we'll want to do a safari. Other than that I'm trying to map things out.
I like to experience the nightlife of every place I visit just to get the vibe, too, if y'all have any recommendations.
I think they have some safari places near Jozi but if you want to do THE safari its like a 6 hour drive from there, its called Kruger national park. How many days are you going? If you not going for a long time might want to just stick to one place. I prefer the nightlife in Jozi to Capetown but you probably need to know somebody who lives there to find good places to go. Really you probably need somebody who lives in Jozi to have a good time, I don't remember it being touristy. I knew people who lived there so I had a great time. One of the best places I've been.
