Was just going for the exact sentiments of #3. I would not be anything with a complete head cover. My cousin was either Chip or Dale for several summers, and apparently she got used to the heat, but not for me. I'd be a princess. Belle, probably.
I would be one of the Disney Princesses. Besides getting to wear a glamorous gown and receive hugs all day from adoring fans, the Princesses get to be in the nice air-conditioned building.
As a guy who doesn't have the body for going around without a shirt, I'm in trouble. No Aladdin for me. I guess maybe I would be Winnie the Pooh. I could run around in the costume and take pictures with little kids and not have to say anything. I think that would work...
