Funny thing about the 15's. My husband and I were placed in a building at Pop Century in February completely surrounded by them. We got no sleep, it was awful. After four nights of calling to complain (security would show up, they'd quiet down briefly then start again) and not being able to move us, Disney gave us three free nights to use on another visit plus a $100 credit on our account. We booked for December. Sad to think we may not get to go, but I am just mean enough to be happy the groups may not get to either.
