Hi, I read thru some of the posts, thank you, need additional advice. traveling with a child 9 years old. flying from cairo to kili in june, thinking of stoping in nairobi for 2 nights to see the animal orphans, david sheldrich, giraffe center. Is this a good use of our time (child loves animals)? I read advice is to stay in "karen", please recommend a mid-priced clean safe hotel? how far from "karen" to airport? thank you!
