Hey Camel,
To save a few $$ on lift tickets, purchase them at the "7-eleven" convenience stores in YVR. You'll save anywhere between $20-25 Canadian per ticket. There are a few stores along the drive to Whistler/Blackhomb (ie Squamish), but the offer isn't valid. It's cheper in YVR because the "locals" buy them there then drive in.
As for hotel accomidations, I am sure they offer discounts with your airline i.d. Call or e-mail before you go.
Cheers.
