To change or cancel a lift ticket date, please call the Epic Pass Service Center at 970-754-0005. Whistler-Blackcomb guests call 800-766-0449 or go to the resort ticket window by 5 pm on the expiration date of the lift ticket. In addition, be aware that two or more day lift tickets have a range of dates of use, depending on the number of days of the ticket. For example, a two-day ticket can be used anytime within a three-day range. A three-day ticket has a five-day range of use, etc. Stop by a ticket window for more details. Also be aware that lift-ticket sales are limited this season to enhance the on-mountain guest experience, so lift tickets could sell out. We highly recommend purchasing lift tickets in advance. If a resort is not sold out, lift tickets can be purchased online or at the resort, but not by phone. For more information, please go to Snow.com, Tickets (top, center), and then scroll down to FAQs.
