Just to name a few. Windells is full of shitty, self-centered, spoiled rich kids. A lot of the pro's/coaches aren't really there to coach. They get paid to ski essentially so that's what they do. But it depends who you get/which session you go to.
COC is a lot more learning oriented and everyone I met at my short stay there was really nice, and helpful. Not as much big-dicking that you'd see at Windells.
