Glad to hear your going to Whistler as well (for the first time too) though approx a month after me, I really wanted to be skiing there on Australia Day (Jan 26). It should be an experience alright, & know doubt a lot different to what I am used to here in Oz.
Hope my legs hold out, I normally only get 4~5 days on the snow here, (it's a fair distance + $$$) where as I am having 10 days in Whistler then another 7 in Fernie!
Might have to have some down time & check out the coffee shops - hope Canadians can do a decent Flat White!!
Anyway hope you have a great time over there to.
