I have some pics of the tower at Disney, from a few days ago. (I was just there, and went on the ride.) They have a NICE interior to it. It looks abandoned in the beginning, but in the end where you walk out of the ride looks clean and not abandoned. Also, the way to the service elevator is first the Library, then the boiler room type of thing, THEN the service elevator. They showed you a hallway as well when they first took you up in the ride. It had the door at the end, and the eye or something. I don't remember now. Really cool. (And I love the show :3)
Also, I would love to help with the acting and stuff. And possibly building. I like Art Deco, which occurred when that took place. I also suggest using the Old Timer or the Kapitan because those cars are from the 30s/40s and would look better in my opinion.
Edit: stuff, re read OP. Different stories we are talking about here. So I wouldn't be any help.
