I've got my airline tickets booked to go to Tanzania and to come back. I leave April 24th and return on May 6th. That means I have almost ten days of actually being in Africa (counting late evening of the 25th and most of the day of the 5th). That should be enough time to see Arusha, go on a small safari, and hit Zanzibar. Annelies will plan things out before I get there.
Next step: get immunizations updated (yellow fever and typhoid) and get some malaria medicine to bring with me, and send my passport off to the Tanzania embassy to get my tourist visa.
First, the UK, then Europe, then Central America, and now Africa. I guess I do get around.
