I belong to a club called the Mogul Meisters in Westchester County, NY. IN addition to 3 or 4 weekend trips to VT we also run a few week long trips out west and just added a European trip this coming season. Off Season activities include pool parties, hiking, biking and rafting excursion, wine tastings, getting together at a local music festival, etc.
We don't have any kind of a lesson program - I have not heard of ski clubs who do that. We do get offers of discount lift tickets that can be bought in advance. Also may mountain have a few ski club appreciation days and offer discounted lift tickets to anyone who can sow a ski club ID.
This season I am going to Jackson Hole with the club for &1,400 which includes airfare from NYC area, 6 nights lodging and breakfast in Jackson Hole and a 5 out of 6 day lift pass. I am going to go at a reduced rate as I have already bought the Mountain Collective Pass and don;t need the lift pass; so a week long trip to JH will cost me about 1K not including lunches and dinners.
