WOW! This was our first time during Pop, and aside from the 4 tiny little cheerleaders exiting Space Mtn. sitting on the handrails of the conveyer thing, I didn't really notice too much inappropriate behavior. (of course if I sat up there, it would probably shut the thing down). We were in early every night for a change, since we had our baby with us.
I agree, Disney did the right thing, but in this day and age, it seems like the attitude of parents and, of course, their kids, is that if we didn't win "we got ripped" rather than "the other team played better." Likewise, my kid got in a fight, but there should be no consequenses because we have other children who might be inconvenienced. Those parents should realize that their big kids could have done a lot worse to someone else's precious little ones that wake them up by fighting in a very crowded place. One big football player steps on, lands on, etc. . .a one, two, three or even 10 year old and a lot of damage could have been done. That is not even counting the psychological damage of seeing a brawl on Main Street. My little one is too young to know, but I have friends with older kids who would NEVER want to go back if they saw a mob scene at Disney World.
I doubt Disney would cancel the contract before 2010 (what do I know, really) but since it sounds like these things are escalating, maybe they will consider not renewing.
