Replying to Sunshine, Norquay, Louise, Panorama, Kicking Horse

Whats up all, my girlfriend and I are planning a trip over New Years and these are the areas we're looking to go. We're looking at Dec 26 through Jan 4th, flying into Calgary from Seattle and renting a car. At this point we're thinking 5 or 6 days in Lake Louise and 2 in Panorama, skiing all the areas in between. What do you all say? Would it be better to stay in Banff or Lake Louise? Should I ignore any of the areas? Which town has better night life? Terrain? My girl is a pretty good rider so I'm not looking for greens and easy blues, but cruisin' and riding the park is allways fun.

Thanks for your help.
