The behavior from the cheerleaders has, IMO, greatly improved over the past few years. Thinking Disney made some changes in the rules because we only had one issue for two weeks, and it was with the chaperones, not the girls.
Oh gosh. How many competitions do they have down there ? We would go the second week of December for a few years and we ran into the Pee Wee Football National Championships every year. Parks were overloaded with little footballers AND their cheerleaders. I understand that everyone has the right to go to Disney, but some of these big groups are just obnoxious and think that they own the place. Be polite, be courteous, and try to make everyone's visit magical.
