Jack, I did the Segway tour with Stacerita, and a few other Dis Ladies on our trip in March. It was a blast. You get training on how to operate the Segways (which is not as easy as it seems, really). And then you get to take a tour around the park. My favorite place was when we got to ride through the Redwood Creek Challenge Trail area.
You aren't allowed to take pictures during the actual tour because they don't want you using your camera while operating the Segway and technically, the park is closed so you can see some maintenance CM's and other 3rd shift CM crews working. They also take you backstage at one point (very briefly).
They do take a group photo afterward and we managed to get a few individual shots at the end of the tour.
Let me know if you have any other questions. I'd definitely do it again -- it was really neat!
