My BFF works at Hollywood Studios (part of DisneyWorld in Orlando) and she's, golly, about to turn 50 and she loves it. I don't think age is an issue as much as your attitude, and if you like Disney, you'll probably like working there.

As an aside, nearly every time I visit Disney and buy something at one of the stores, the clerks ask me if I work there -- the employee discount is pretty good. I've got a Disney face.

I say go for it. At worst, you could have a fun summer job blog about it.
