Looking to go to Kenya on Safari with my college age daughter in July/August for 2-3 weeks. There are soo many tour companies to choose from. What is a good one to check out? I don't need fancy hotels- am willing to sleep in a tent on a cot or in a sleeping bag. I am interested in seeing the migration, the crater and Masai Mara. Any help would be greatly appreciated. Also- for those flying over from the Northwest (out of Portland, Oregon to be exact) what airline has the best pricing?
