On our last visit in Feb, there was a large group (mostly female) staying at ASMo. We noticed them in the parks, and didn't realize they were staying at the same site until we were behind them in the bus line one evening at MK. Their chaperone "commandeered" a bus to keep the group together, so we gladly waited for the next bus that time around.
Granted, the young women were polite while in line. Several of them were trying to make conversation with my exhausted little boys. Other than acting like typical teen-aged girls, we saw no negative activity.
