I m living in Lausanne just 60km from where you re staying right now. You should definitly go to Avoriaz in France (by les Crosets CH) or Glacier des Diablerets to shred park but even there you won't find anything big now. I think there's a liittle 3-5 jumps line and few boxes.
But...There's so much powder everywhere right now. You could easily find some really fun terrain in Villars. Nice cornices, cliffs and small lines whitout hiking more than 10 minutes from the chairlift (I m sure you did not try the old "petit chamossaire" chairlift in Villars yet). You should also go on the "Barboleuse" side and ski the whole run in the forest. But be really carefull if you go offtracks right now cause it's more dangerous than ever.
How long are you staying there? I wasn't expecting to go skiing that much this month (shitty exams!!) but if it is to show some places to a fellow NSer I could maybe take a day off and shred POW with you!
