I can't see TB staying more than one (1) night in Cape Town other than to rest up. The Cape Grace is marvelous, but I can't see them filming there! JMO. The train is GREAT, but too public, imo. Can't see them going to Kruger either ... too public and waaaaaaay too many tourists.
My choice of private reserves of SA:
Earth Lodge Photo Gallery | Luxury Safari Lodge Photography | Sabi Sabi
Zuka Lodge | Phinda | South Africa
The Homestead | Phinda Game Reserve
Londolozi.com || Granite Suites
The above also have "cheaper" rooms for staff too. Plus, they are all about conservation, schools for the children, jobs for the people, etc.
Maybe: Mala Mala or Ngala
My roommate in college was from SA. I adopted her as my "sister". She went with my family on all our trips/my house for years and years. Her family adopted me and I got to go to SA all the time. Good trade!! lol. Her family owns a Travel Agency in SA. I have asked about TB and where did they film/go. They won't tell. The so respect privacy.
I cannot see TB going to SA without a trip/date to the Great Zulu's or the Shangaan's. There are great cultural villages to be explored. I can see Brad meeting a Chief. Each wife costs 11 cows. Chiefs have many wives. They don't adjust for inflation/recession either. I asked.
Also, most of SA have landing strips everywhere. You just have to radio ahead to get the critters off the run way. Phinda has the Flight of the Fish Eagle. They will fly you over the Elephant Coast, watch hippos walk under water (they can't swim!!) to over the world's most vegetative sand dunes to the warm, beautiful Indian Ocean. Once you land, a land rover picks you up and you can go anywhere you want. SA's motto is Dream a Dream... they'll make it happen.

Hopefully this is not OT or wrong area. If so, delete or move. Once you get more SC, I "might" be able to help?
