We also did KTTK, in 2003. Worth it. You learn the level of detail that Disney goes to in order to make sure that everyone has a good, safe time. It was fun being briefed on how some questions would be answered in public, versus backstage. We'd also like to try the backstage safari (perhaps I'm getting the name wrong) at AKL. A colleague of mine has also done a tour at Holiday time: she saw behind the scenes of several parks and their holiday decorations, as well as the storage facility for the Holiday decorations.
