Tickets cannot be picked up in advance. They must be picked up in person at the resort on the start date that is listed on the order confirmation.
A multi-day or X of Y ticket (e.g. "Crystal Mountain Two Day Pass" or “Sun Valley 3 of 5 Day Pass”) must be picked up and used on the start date listed on your order confirmation, however it will only have to be picked up once.
When purchasing multiple 1 day lift tickets, you will have to visit the ticket window on each start date.
