Pop Warner is an event when thousands of football players, cheerleaders, and their families come to WDW for a superbowl. They mostly stay at value resorts but some stay at moderates. Usually the Friday night of the week they are there, MGM is closed down for everyone but them. I think the kids range in age from preteen to high school age. I believe they will be there the week of December 4th. There were rumors a while ago of them changing weeks, but I don't think that happened. If you do a search on these boards you'll find out a lot about it and some of the problems people have had with the kids behavior.
