If you are renting skis you can get a 10% discount just be asking for a discount (at least that was the case at the ski shop across from the gondola). Maybe your week in Jan. will be a slow week and prices will ease a bit, over Christmas/New Years it is very expensive. However I do think it is the best resort in the Americas, huge area of ski-able terrain but pay attention to the wind and cloud conditions. Quite a difference between areas and really affects the ski conditions. Thankfully Whistler has been getting rid of some of their extreme moguls and flattening the slopes (which are quite challenging as it is, being the 2010 Olympics site). I am a poor skier (lack of practice as I only get to ski a few days a year) but Whistler is great fun. Well worth the trip. A good skier would get a lot more out of it, some really great (but difficult) slopes there. BTW Creekside is the original Whistler, then the developer ran out of room and got the bright idea to move the resort one valley over and we have the modern Whistler; you can take the lifts up at Creekside and ski over (much cheaper to stay at Creekside, though I haven't done that, only stayed at Westin which is OK but not great except for the location).
