Something to do while you're there: The restaurant at the top gondola station (not the Peak) on Whistler has a "first tracks breakfast" deal each morning, whereby you get to have an early ride up, eat breakfast while the ski patrol bombs the cornices, and then hit the slopes just as the lifts are opening for general use at the base.. Really cool to do on a morning after a snowfall.

I think this requires day-before reservations.

Cheers
