Hi,
I was on this board last summer looking for info on climbing Kili. I ended up going last August with Good Earth Tours, 7 day Machame route. Good Earth were good, I'd recommend them. I joined a larger group who had already scheduled the 7 day trip, but on the day only 3 of us were climbing, the rest canceled I think. All 3 of us made it to the summit without any trouble. I was glad to have done the 7 days, 6 days would have been too hard and I know I wouldn't have enjoyed it as much.
I finally put some photos of the climb online at http://finelookingplanet.com/gallery2/m ... emId=14160

I also did a safari with Good Earth, also recommended. The Serengeti was a dust bowl in August, better to head into Kenya at that time of year I think. Stone Town in Zanzibar was really lovely, other travelers had told me to skip through quickly to the beaches, but to me Stone Town was the highlight of Zanzibar. Each to their own I suppose.

If you're looking for independent unbiased information on climbing Kili, a friend of mine just did it and put up a website about it at http://www.mountkilimanjaroguide.com/. Enjoy!
