I used to cheer in college and they have competitions in January through February. High schools and colleges compete at the complex there alllll the time. Also, a lot of mid & high school chior, band, and other "performing" groups go during these months.
You can call to find out what and how many groups will be there at the time you will. If you find that you will be there with several other large youth groups I'd ask about an upgrade to another resort. Maybe a moderate resort.
Good luck!
