In reply to kos_os:
I did a season in Fernie.
banff is great, the area as a whole is colder than whistler (or fernie) so if you dont like quite extreme temps then maybe go somewhere else (we had a couple of weeks of -40c which sucked).
shouldnt have a problem with work, the resorts put on a job fair and fill all the vacancies then. just dont be picky about which job you do. i was a liftie which was the best job ive ever had and likely to ever have.
we worked 4 long days for minimum wage and then got 3 off to ski (board), it was amazing.
fernie is a good alternative, medium sized in the grand schemes of canada, nice town, good hill, great snow.
dont bother with whistler, you wont find anywhere to live.
