My experience with cheerleaders/dance teams/whatever you want to call a gaggle of overstimulated teenage girls at WDW is as follows.
Twice we stayed at the All Stars, once first week Feb, once last week Jan. Both times the place was over run with them.
From 6:00am until after midnight they'd be outside our door praticing. Calling the desk did nothing.
Those who weren't practicing we taking up tables "hanging around" the food court, or rough housing in the pools.
Try getting on a bus, they'd cut in front of you with a real entitlement mentality.
They'd cheer on the busses, in the parks. There was no escaping them.
We couldn't nap in the afternoon, they were practising outside our door.
It was brutal.
We decided never again........
The point is that even with "alert" chaperones, it's still unfair to other guests to have to deal with a large group of teens. Regardless of how polite they are, by their very nature they are LOUD. As I said in the other thread, Disney should set aside a resort just to house student groups. This would cause the least amount of disruption to other guests who have saved and worked to take their families to WDW.
