We are going to WDW in 9 days
One of my favorite things to do is go to Disney/MGM/Hollywood and go to the animation studio and see what they are working on. I know they moved the actual studio since then, but they did have posters and production items for up coming movies. There was nothing like seeing Mulan and Hercules in pre-production.
I will see what they have in store (I can't recall if you can bring a camera in there, but we'll see).
