In '03, I stayed at Music at the same time as the POP kids. They were loud at times, but not a big issue. While riding the buses, later in the day, they were a bit rowdy. Now I've been to WDW a few times at the same time and they really haven't impacted me much. They tend to be in the parks at night, since they are in competitions during the day. Yes, they can be less than polite. But, and this is what really surprised me....I was at WDW in late May a few years ago. There were a ton of 'groups' in Epcot....youth groups, camps..that sort of thing. And they were brutal. YOu had to hear the mouths on some of these kids...they were rude, obnoxious, pushy. Evidently, May/June are big months for church/school groups in Florida to head to Epcot for the day. Then, when we headed to Tampa at the end of our WDW stay, we ran into more of these kids at Busch Gardens. Hard to believe but they were worse behaved than the groups at WDW...actually saw a spitting contest while in line for a ride...and it included both sexes!!! You would have thought that groups with the name of their affiliation on the shirts would have had better behaviour. I wanted to write down a few of the groups' names and send off a letter to the appropriate church/school and let them know how badly behaved their kids were.
The POP kids paled in comparison. I'll be there with them again this year. I do arrive towards the end of their stay so I'm not overly concerned. They really haven't impacted me adversely in the past.
