I have stayed at WDW resorts probably 40 times in the past decade....I have had ONE single bad experience, and that was a big teenage south american tour group at Riverside...the screaming, shouting, banging, clanging, and partying started about 8 pm and went on until the wee hours of the morning. They appeared to be unescorted, and at one point party central, the room next to mine, had (no kidding) more than 30 kids in there. I called security three times, and after the third, I called the front desk and they arranged a new room for me in building 85. Zero problems from that point on. I have to say that out of 40 trips, 1 night of rowdiness isn't bad, considering you go to a college football game and stay at the team hotel and the party runs 24/7 with just as much noise. I would bet though, that the adults in that tour group got an earful from Disney the next day.
