I was a member of the Wisconsin Marching Band, and in my time, went on 20+ trips that required a hotel stay.
Let me make one thing VERY clear. When you are down there with a team, or in support of a team, you are there to WORK. You not only represent yourself, but your team, your school, and often times, larger bodies - such as your state (notice how the states were named in the article.)
If you do something stupid like fight, you and your whole team deserves to go, as your team has lost focus and discipline, and therefore should not be a representative group. Doing something like this is very selfish, and shows no caring for anybody but themselves. Those that run these teams should have instilled that sense upon them, so I do not feel sorry for the adults that had to wake up kids in the middle of the night - only those young kids do I have any pity for. If the people have nobody to answer to, (at times I've seen parents encourage rowdy/rude behavior, using the excuse of "team spirit" to further their arguments - but that's another discussion entirely), then they will not feel a sense of responsibility to their group.
When we traveled it was made very clear that we were there to support the team, first and foremost. If we did something stupid, it would not only make us look bad, it would make our team, our university, and our state look bad. You are under a microscope when you go on these trips, and you have to have that sense of responsibility. If you don't - stupid stuff like this happens.
I'll bet they don't make the same mistake again.
