granted, this wasn't for Disney...
My son's team made it to Odyssey of the Mind State Finals this past year.
I was so obsessed with making sure that we had all of the props, costumes, paperwork, etc. I left EVERY single bit of our clothing at home, except for a small bag of pajamas and underwear.
We had everything on hangers because we were going to have a tight schedule and no time to iron anything. All hanging clothes were left laying on the bed.
Thank God for Target.
