We went a while ago but we rode on the Haunted Mansion and Big Thunder Mountain. It was really neat to enter behind the scenes at the Haunted Mansion. We were in the corridors where the cast went and passed one cast member on the way. I can't remember anything behind the scenes at BTM, but that's not even an option, sadly, now.
The tour was well worth it if you are into history of Disney and some behind the scenes things.
