I got to take my daughter through this as well, in June 2001. It was very narrow and dark and the stairs were steep in some places. She is weird about stairs and it was kinda miserable. She did better at Tarzan because she could see the stairs.
The displays were very pretty but they were obviously from the early days of the park. They had just kinda been kept up but not added to or improved in the last 50 years. It was nice...and she was as a Sleeping Beauty fan so I'm glad we got to go, but it wasnt that exciting that I am all that sad its gone.
I would love for them to do something with the space though. Inside the castle is a magical place. It would be cool to add something there. Not room for a Cinderella's Royal Table probably, although there is that little store there too.
Does anyone know what else is inside the castle? It is a pretty big space to just have that walkthrough and the one little shop...
