I've been there before! Its a lot of fun! Many people think because they at a small level and are older they won't have fun at all or meet any new friends. There were probably like four or five 12 or 13 year olds in Pepper Jack and about five or six in Colby Jack. Its a really fun camp. What session are you going to? I am going to eight or nine, I think.
EDIT: It just dawned on me that you've never been there so you wouldn't understand the group names

Pepper Jack and Colby Jack are the two easiest groups (Pepper iss easier than Colby) Pepper Jack usually has level 4's and Colby Jack has level 5's and some 6's. The groups keep working up in diffuculty. There are 6 groups and you go through 4 rotations of about 45 minutes-1 hour every day. The five "events" you do are bars, beam, floor, vault, and dance. On the last day everybody shows eachother there dances at the exibition. Parents come too. Its really fun.
If you need any more info I would be happy to answer your questions
