The trips change slightly year to year, but you'll find the basics checking out sayhello's link to the sticky and Mike's photos. My DD13 and I have been on this tour three times and we loved each one, especially our summer 2012 tour taken with the DIS Unplugged. (And we've been to Disneyland too many times to count.) If you have any specific questions, please ask.
What a great thread. Its almost as though I was there with you. oh wait....
We really enjoyed this trip. Just the behind the scenes stuff was enough to blow your socks off. Add to it the special access to the Jim Henson Studios, the Walt Disney Studios, and special in the park experiences and its really a great trip.
