If it is raining or you just want some quiet time while in Whistler a great place to visit is the Whistler Public Library. There are books, dvds, VHS Tapes, magazines, computers, Internet, and board games. If you have your skis or snowboard there is even a lockable ski rack in the entry way with locks available at the reception desk.
A list of activities and events is available in a little book upon entry. A meeting room is also available for $40 per hour and it even has a little mini kitchen.
So if you need to escape your Whistler accommodation try the Library! You won't be disappointed!
