Awareness / Club Days are discounts offered by the mountains to all CSC members (Winterset Members with a membership card). You take your Winterset Membership card to the mountain listed on the date listed and get that price for lift tickets that day. Each person buying a ticket needs a membership card to get the discounted price. See CSC Website for details for each mountain.
Bulk Buy Vouchers are bought pre-season and turned in for lift tickets at the mountain, there are no specific dates, for Bulk Buy Vouchers. Bulk Buy Vouchers need to be purchased in advance and are only available for purchase during a very short window in September.
The Awareness / Club Day schedule can be found on the Connecticut Ski Council's website:
