Do not stay at Riverside during Pop Warner week! I worked in the food court at that time... the lines are longer than most any other time of the year, and the kids are loud and out of control. Aside from how I felt as a Cast Member, guests kept asking me what was going on and why they were so loud and after they left, the guests kept commenting on how quiet it was now.
I know they stay mostly at Riverside, and I think one other resort. They were banned from one other for destoying stuff. Any other time of the year I would tell you that you should stay at Riverside because it's wonderful, but you'd be best picking somewhere else to stay during Pop Warner week.
