The snows going so you will be stuck with all the big resorts, places like Ibergeregg etc will be very low on snow. We are in March now so most the purist have hung up thier Skis its just the Auslanders skiing now.
But next year try either heading out towards Schyz (Ibereregg, Rigi, Stoos) or Toggenberg, (Wildhaus, Santis) both quiet areas.
