I need to think of more activities to do for my disney-themed sweet sixteen! Help?

I'm having a disney themed party for my sweet sixteen, and in terms of activities the only things I planned are movies and dancing. I want people to have a good time, but I think they need more ways to occupy their time. Does anyone have ideas on disney related games or activities that could work for my age group? Its okay if they seem like they're more childish, a lot of us act like children anyways. Please help me!
