I've gone - i would 100% recommend it !! It's so much fun, and you progress so quickly. Surrounded by so many other park skiers all learning and trying new tricks, its crazy how much you can learn in 6 days. I always really liked the coaches there too - guys like Bibby and Dorey are reallllly good with breaking down the trick. Their park last year was so good - the jumps were perfect for learning stuff on.
tl;dr, do it haha.
