I think Walt Disney World is one of those places where age doesn't matter too much. It's the one place where you can forget that you may be a 9-5 hotshot at some business, or whatever. Our girls are little and they like that stuff. I went my first time as a teen and I would've hated that, but now that I'm an adult I think it's great - although we don't go crazy with it. It's all up to you and the kids. Get their input on the subject and see if you can come to an agreement, and if not....wear what you want to wear and let them wear what they want to wear. haha Makes for great pictures at the very least. ;-)
