I just returned from a 2 weeks photography safari to Tanzania. The trip was fantastic! I will blog about my experience over the next few weeks. In short, we woke up on average at 5 am and went on a daily ~12h photography drive, taking on average 700 photographs a day.
The one tip I have for anyone planning a similar trip is to take at least 3 times the amount of disk storage that you think you will need. It is amazing who much disk space a couple of Canon 5Ds and one EOS 1DS II can consume in a single day. I kept having a recurring dream of finding an Apple store in Tanzania to purchase additional HD space - not good.
For anyone who loves wild life photography this was a dream trip - we did nothing but photograph every thing day, all day, for 14 days. We were completely unplugged from the world, no internet, no newspapers, no radio, no TV. Our whole focus was on photography.
We visited 5 major Tanzania National Parks, and in the end I had captured "The Big Five".
I will post some additional photos to my web gallery in the next few days.
