Anywhere in the SW corner is pretty dope.
Some of the more major/popular ski areas include:
Zermatt, Interlaken, Laax, Daos.
Check out Zermatt and Saas-Fee for year round summer park riding. Switzerland Ski Resort Map
Check out the southern region (Ticino) for your non-snowboarding vacation part of the trip - it's italian speaking, really nice people, and cool villages... less of the schnobery that's up in Zurich area.
If you're heading out to party I'd suggest Milano, Italy.. pretty close.
Remember, it's pretty expensive over there.
