Replying to Skiseason advice in North America? Mostly powder.

Next year Im planning a trip to North America too go skiing a whole season. After watched thousands of edits and movies over the years, Im finally gonna get my ass over the atlantic ocean (from Norway). I have skied park and powder for about 8 years or something and looking for a good powder ski resort. With much natural playful terrain and good snowconditions. A terrain park is a plus, but not necessary. I have watched edits from Alta, Big Sky (US), Whistler (CAN) and so on. They are looking nice, but I dont know how much crowded they are? Im also capable to do some small hiking to find good spots. But I certainly prefer mainly to take the lift! A small place is also a plus for me (village, town). I have no idea whats best, but hope I get more suggestions from you guys. I would like to stay at one place and maybe move around. (Several resorts in one skipass?)
