I went and I was (am) pretty new to park. Sure, there's plenty of kids who absolutely kill it, and a few of them are probably gonna be dicks. But there is also a huge number of mediocre/beginning park skiers that just wanna have a good time, learn and progress. As long as you don't care too much about looking dumb trying to learn simple tricks in front of your favorite pros, and 13 year olds who can double, you'll be fine. I had an incredible week, fit in fine and learned a ton. Just don't be intimidated
