If we've got a couple of days to spend at the Magic Kingdom, we do try and work Storytime in. If you're going, be sure and get there early, the seating is very limited. Basically, it's a long wait to see Belle read her own story with help from kids in the audience. We've never gotten picked to "help" with the storytelling, I think that would make it even better!
The time schedule is in the park map, I think.
Have Fun!
