So since I've always wanted to cosplay as Riku at Disney World, I've just made arrangements to do so, and I will not be alone. Behold:
Project Magic Kingdom Hearts.
Wherein a horde of KH cosplayers will descend on the Magic Kingdom during Mickey's Not-So-Scary Halloween party, the one time of year where you're allowed to dress up in costume and run around the park.
The middle elder sibling and I will be there. Anybody else want to come along?
