How much did you pay for your Safari? How long is it? Did you pay for a private one or are you able to join a group.
Man I really wanna go to Tanzania this year and do Kilimajaro/Safari/Zanzibar. The longer I wait the more prices seem to shoot up every year

For Egypt the only advice is that you're going to be hassled non-stop from when you land to when you board the plane. I'm a pretty seasoned traveller but Egypt was on a whole 'nother level. We went in May 2011 right after the revolution so we were like the only Tourists around even at the Pyramids. I hear things haven't improved much since then.
