Kelly's suggestions are fine. You might also consider Lech or St. Anton in Austria or Courchevel, France (pricey), just to name a few. You want to get somewhere fairly snowsure, that is, high elevation. Don't believe Chamonix is known for copious ski-in/ski-out.

sells trips, but their database on resort info is a great place to brainstorm and do independent trip research.
