i have to say we freaked out when we learned we were there at the same time as POP last year. Stayed at POR, so not a ton of them there, but we did have to call security one evening on some of the cheerleaders. they were right outside our window and screaming, running, stomping at 11pm at night- we had a 2 year old trying to sleep. we asked them nicely twice, including the parents to calm them down, be quiet or move somewhere else to go run around, but to no avail. Security finally came and it got better.
other than that one incident, no problems. Most were respectful, especially in the parks and we saw very few of them in the parks, mainly at the hotel. The ones at the hotel were mainly by the pool the majority of the time. i think i would definitely bypass the value resorts that week though.
