My kids also love the kidcot stops. The last time we were there the masks had a star attached to them. You poke out the middle of the star, make a "dream", and throw it in the dreamcatcher nets that the characters carry at the beginning of the parade. It was a terrific way to get the kids to interact with the parade characters.
Unfortunately, my 5 year old DD "dreamed" that she was going to get all the princess Barbies. She was absolutely convinced the princess Barbies would all be waiting for her in her room when we got home. It took me 3 days to work up the courage to shatter her Disney dream. But she got to buy a Barbie as a souvenier and was very happy with it, so it worked out fine in the end.
