If you wanna stay in Canada you get couple choiceand you can mix them up too.
coastal bc : Whistler blackcomb really touristic,= line up, lot of terrain,sick park, huge resort, lot of night life, really good early season snowfall so it's a good bet
interior bc : Revelstoke is amazing, lot of terrain, good snow, good early season, no crowd so no line up u just run into the chairs in week days :P but on pow day wake up really early because the line up at the bottom is huge and you wanna get those fresh tracks, dont miss out, 7 am 7 -30 in the line up! nice town, good restaurant, night life is growing it's all right , No park but i dont think your dad is into park skiing , lot of hucking everywhere anyway
kiking horse conditions are pretty much as good as revy , the town is a little less charming
white water ,nelson,is really nice town 3 hours south of revelstoke so if you want to mix , conditions are really good , hill little bit smaller than the two others in term of vert but still lot of terrain and amzing pow. best caferia in a ski resort , they have the best food for sure
no crowd no line up
than there is red 1-2 hours south again which is also amazing . No crowd no line up
if you wanna hit a park and have good pow and be in the interior , big white and silverstar are close from kelowna airport and still close to revelstoke which is the most in this list according to me since whistler is over crowded.
so overall whistler is a good bet for a good groomers, in bound powder and easy to access backcountry, and you have a park . Mais il y en a au quebec aussi , niaise pas et va skier de la vrai pow
But in the last two years interior BC have get the biggest storms in the first two weeks of january so Revelstoke win the battle!!!!
