We have had problems over the years with other big groups. Some of the cheerleaders have been the most annoying but it depends on how well they are supervised. We usually head away from the big tour groups. Our biggest problem was at Epcot before illuminations with the Brazil groups Arriving last minute and crowding in.

Would Disney really let them book rooms if they TRASHED them? . So far at POP I haven't had any problems. Have at Riverside and that's when we stopped staying there.
