I am planning our first trip to Kenya and Tanzania for 3 during summer 2011. We are looking a private tented Ker & Downey, A&K, &Beyond, but prices vary madly for 11 days. So do their suggested locations. 2 of 3 tour operators say that Ngorongoro Crater is too touristy, but this may be our only trip to Africa, so is it a "must see"?. Also, one highly recommends Lewa Conservancy and Amboseli over the Sarengeti. We want luxury tented camp experience, but also want some evening interaction with other couples at camp. Any suggestions for tour operators and locations to visit??
