I used to be a custodian at Walt Disney World. AMA
I worked at the Magic Kingdom from 01/2012 to 05/2012 on an internship. I've seen it all and I will answer anything as long as it doesn't involve company secrets and the like. Proof is my main entrance pass with my name and hire date, as well as a photo of me at work. http://imgur.com/a/9icSk
EDIT: I will also answer any parade related questions, since I worked those as well.
I'd like to thank every single one of you for your questions! This was really fun to do! I'll still answer any more questions that get left on here but am leaving this message here since it has seemed to die down. Thank you all again!
