I would also choose Magic Kingdom. I would have my family, MIL, FIL, SIL and her family, my sister, friend "S" who loves Disney as much as I do and her adult daughter. I would also find 100 other random people throughout the day just to spread the magic. We would do all of the attractions, pin trade with all of the CMs, snack on all of our favorites and take pictures. We would (hopefully) meet rare characters, chat with CMs and go backstage. We would tour the castle from bottom to top and have a special wishes and parade just for us. (boy, that's dreaming big, huh?)
Question: If you were trapped in a park in Disney overnight and the CMs didn't know you were there and you couldn't do attractions, turn on lights, etc....what would you do?
