I say go for it. Although I dident live at Breck I lived at Big White in Kelowna BC for 5 years.
I was lucky enough to meet some people at my job who went up there every year so I had a bit of an in.
I cooked, washed dished and even did housekeeping to make money. Living conditions sucked, it's a matter of affordability so expect so share a place with a heap of people. I had a dude living in my closet, guess it sucked more for him but I could hear him beating off sometimes...Partying can be fun and be a problem at the same time, every one is there for a good time, so expect a lot of hungover days at work.
But riding as soon as you step out your door is so worth it. I could easily do it all again.
