We've done a number of them, most of which have changed since we've done them. We did the one at WDW, I think it's called behind the magic? At the time we did it, you got there fairly early and walked around with your group, rode some rides and had lunch, went in the underground. Not sure if they ride the rides now. We also did one where they took you to all the parks (I think there may have only been 3 back then), did behind the scenes stuff at each park and rode some rides in each park. It was like 7 hours so of course lunch was included. That was back when HS was MGM and a working studio so you go to go behind the scenes of the actual studio. They don't offer that any more, I do think they do the ultimate thrill ride or something like that. We did the Behind the Seeds tour at The Land in Epcot a couple of times, it's cheap about $20 and there are discounts and we really enjoy it. It only takes about 1/2 hour or so. We've also been diving in the Living Seas a couple of times, they walk you around the inside of the Seas pavillion and show you a lot of behind the scenes stuff there before you dive for about 15 or 20 minutes. Kind of expensive but fun if you are a diver. We've done the Wanyama Safari at AKL, which at the time was only for people staying there at the lodge but now I think everyone can do it. We got before tour appetizers then went on a personal safari on the lodge grounds then had a huge group dinner. Well worth it. We love doing them, as you can see, and will most likely do the Wild Africa Trek next time we go.
