DH and I did this a few years ago and thought it was great. We met our guide Paul at the entrance of the AK very early in the morning. He drove the van behind the scenes, which was pretty interesting. We visited with the elephants, rhino, giraffe, the food prep area, the operating room at Conservation Station and touched an alligator. The tour ended with our own private ride through the Kilimanjaro Safari. Instead of the "Little Red" soundtrack, Paul gave us more information about the safari itself.
Great tour, but I believe there is a minimum age limit of 16 years old.
