I read that writeup as well and it sounded great. I'd like to hear more about it too. I've been so impressed with the reports from Ngaire and the ROAR folks re: Singita.
We did a tour of Tanzania and Kenya in 2002 and really loved it. I would definitely go back. Tanzania was more appealing to us than Kenya in a lot of ways. More unspoiled, I guess, would be the way I would have described it. Although maybe some of it was that we loved the tented camp we stayed at - Kirawira. And I'll be honest and say I would have been just as happy to skip Nairobi.
We haven't done South Africa yet but folks I know who've done both say the SA trips are definitely more luxurious overall. And I think perhaps less unrest in SA. We flew in a day early to Arusha and stayed overnight at the hotel. The next day we saw lots of folks walking along the road and found out that they were going to the market in the village just down the road. We wanted to go but the guards at the hotel practically had a stroke and just about pulled us back in. They didn't even really want me to walk a few yards outside the gate to take pictures of the coffee plants. When we questioned our guide he said that the guards probably over-reacted but that a very small element of the population resented what they saw as "wealthy tourists". Reading the ROAR reports, I definitely did not get that same feeling about SA. On the other hand, we never experienced anything of that nature after the first day. And we never at any time felt insecure or unsafe in any way.
