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...
