I'm not directly a part of it, but have been to WDW several times before when these things have been going on. Typically most cheerleaders can be found at the All Star resorts and, I guess maybe now, Pop Century. There also seem to be a fair amount at some of the moderates, most notably CBR. The good news is that, while the resorts may be a bit more crowded where they are, I have generally found the college groups to be much better behaved and courteous toward other guests than their high school and elementary school counterparts. That's just my experience, however. I'm sure there are others who have different stories. HTH.
