Replying to Plans to bum in whistler, need advice

Last year I went to whistler for the first time and even when they had minimum amounts of snow, there is no other place I could see myself living, so I couldn't imagine how I'd feel when they have as much snow as they do now. I live in nh at the moment and whistler seems like a great place for me because I don't think I could ever not be in the mountains or trees and the village is just nice and modern and perfect. I really think I would like to go out there sometime after I graduate and ski bum for the winter, no work, no school, just skiing. Now with how expensive it is to stay in whistler it'd be optimal to do it with multiple people which I don't think I'd have a problem finding to do so. The thing is I don't know if it'd be best to do it before or after university. I do happen to have Canadian citizenship and would be able to go to UBC and I have plans of going to med school and becoming an ER physician, at least as of now, I'm just not sure how I'd be able to balance everything out. Anyone have some good experience about how to do this.
