Been there +15 times - Nice area, and very good skiing in two countries. Not much happening on the swiss side of area, but the area is taxfree! The area have 90% of their pistes above 2000 meters, so very snow-sure, and a lot of the area is facing north, and ensure good conditions all season! Don't expect anything to be cheap anywhere, since it is one of the more upscale places, but that also means that people get up late, and you have the powder all to yourself until midday!
Let me know i can help you in any way!
