I'd love to be a Disney Imagineer. It would be so much fun coming up with new ways to spread fun and magic, to keep things fresh for everyone. Like, designing different seasonal treats to offer in the confectionary, or CM costume designs for new rides or attractions that will be opening.
VIP tour guide would be great, too. Getting to tell all of Disney's secrets, and show people all of the behind-the-scenes stuff to really blow their mind. I love trivia, especially Disney trivia, so it would be really cool if I got to be around that all day. It wouldn't feel like work.
It would also be cool to be involved with the hiring process, like a Disney headhunter/casting agent (if that's even a thing). I'd be great at interviewing potential cast members.
