a Tanzania safari...
in what order did you do these segments? We were thinking to go to Rwanda first, but that will entail a travel time of almost 20 hours. Don't think we'd be up for a gorilla trek a day or two later.
So now we're considering doing the safari segment (about 10 days) first and then going on from, say, the Serengeti to Kigali and then doing the gorilla trek. This would bring us to Rwanda the last few days of February 2012.
