Used Costco Snowshoe lift tickets this past weekend. Was surprised to learn that I received actual undated lift tickets vice some sort of voucher. Just clip on and go, just remember to clip a new ticket on each day! Cost $112 for 2 tickets.
A note of caution: if I remember correctly, the AMEX deal of "2 tickets for price of one" is for weekdays only. This deal is about $20 per ticket better than the Costco deal.
If there is not a Costco nearby, you might check with your local ski shops, many have special prices on Snowshoe tickets. Sometime this week I will get a trip report out about my fantastic Snowshoe 6 day adventure with my whole family including grandkids. Expensive (but worth it), cold, wonderful snow! Will also include special insight into their Children's Ski School. By the way, this trip they had the Split Rock pool at a reasonably comfortable temperature...a first for me.
