I'm sure there will be a lot of Disney characters, but other costumes as well. A lot of groups/families dress up in theme. I know one group going this year as characters from Peter Pan, my family will either be the Princess Parade (with DS being Gus-Gus from Cinderella) or we will all do characters from Cinderella. Its up to my two oldest girls if they want to wear their Aurora and Ariel Costumes or something else. I may decide to be the Fairy Godmother pushing Cinderella and her mouse in their pumpkin carriage (aka my double stroller!).
