i would say hcsc, haha but this is skiing.
i went to windells for two summers and i learned that it all depends on who your coach is. second year i had a pro as a coach (casey neefus, snowboarder) and like he didnt teach shit, and thats wut i hear from others too is that pros dont really teach they just are there to chill.
so basically it all depends wtu ur looking for. plus they made the sessions shorter by 2 days since i last went. and oh yeah add in money for food, cuz i dont think u want pb and j every lunch. digger dogs are super good and if u get to know the guy at the gril in the timby lodge u can get discounts.
id say go for it.
