Replying to Whistler clubs

I will be in Whistler the 9-13 of January. Not including lift tickets and lodging, how much money should I bring? I plan on going to the clubs but don't realy know how much money to bring since I am not old enough (19) to legally drink in the states and I am assuming everything is going to be alot more ther. The only meals I plan on buying are dinner and possibly lunch.

I was also wondering if any locals had any advice on good clubs and cheap food. Also, does anyone know if the Fireside Lodge Hostel is any good? Thanks.
