My $0.02 on Whistler is it's not that overwhelming having a big ass mountain to explore, besides you want to ride on the blackcomb side anyway so there goes 50% of your choices anyway.
If you want to also check out Baker stay a night or two in Vancouver. Baker is actually closer to Van than Whistler is.
Plus if you puff you wont find better weed anywhere then Vancouver.
baker is getting pounded . I was in 3ft of snow 10 days ago. the next day they closed it down because of too much snow and trees all over the highway
