There is terrific skiing/boarding in the Kootenays (SE B.C.) but I'm guessing those resorts won't have near the size of Whistler Village re the bar/restaurant scene. I'd suggest looking at http://www.britishcolumbia.com/Ski/ and open the "Kootenay Rockies" page. Red Mountain Resort is supposed to be fantastic and is where my older teenage sons are yearning to board at.
Perhaps the Canadian Rockies are the way to go. Here is some info I pulled from one of Judy_in_Calgary's responses re resorts:
"If you do end up choosing Banff as your ski destination, a popular deal is the Tri Area Lift Ticket that covers skiing at Sunshine, Lake Louise and Norquay. You can check out the details here:

Happy planning!
