Sunshine village is closer than Louise. My opinion is that sunshine has better snow and slack country if you like that. Louise has a better Park, at least previous years it has.
Fernie will be tougher to get to. It is 4 hours away on dry roads from your spot. Worth checking out for sure though.
If it is a big dump I hear castle is the place to ride though. I've never been though. This year for sure!
