DH and I have been at WDW during this week before. I didn't think it was that bad. The crowds during the day were fine; you did see more of the kids in the parks and on the buses in the evenings. For me, the worst was the same cheer over and over again. They would cheer standing in line for a ride or on the buses; this was not all groups but there were some. You could also tell the ones running amok without supervision. They were being typical girls in a pack, loud, giggling, etc. I would not avoid this week in the future. Of course, I say this but I need to qualify that we were not stayng at a value resort. I've heard that can be pretty terrible when they are there.
