I don't know the dates but we were there during Pop Warner week last December and had absolutely NO problems. We stayed at Pop Century. I saw a few cheerleaders in uniform at the resort and at the parks, none were misbehaving, being loud, etc. The parks didn't seem especially crowded to me - from what I understand they have competitions going on during the day. I was concerned because of reading about some other folks experiences with Pop Warner week, but I was pleasantly surprised. I heard that they close MGM early one night for a Pop party, I think it was Friday night last year, so we just planned not to go to MGM that day.
