I went in March twice with my softball team in high school. We stayed at All Star Sports, where many other sports teams were staying. We ran into baseball teams, lacrosse teams, other softball teams, and probably more that I can't remember. They were all very mature and we had no problem with them. The only groups that we couldn't stand were the cheerleading groups. They were so immature. You could tell which ones they were by the clothes they were wearing, the curlers up in their hair, the stupid glitter all over their faces, and the loud noises they were making. They were so rude and obnoxious by practicing on the grounds outside people's rooms . . . even at 11:00 pm at night! We were really mad about it because we needed our sleep for our games that were really early in the morning. Thank goodness someone in our group got a manager or something and they made them leave.
We definitely had problems with them at the resort, but the one good thing is that we didn't encounter them in the parks.
