I went to Valle Nevado last month for a week and it was unbelieveable. It snowed 4 feet right before we got there and it was bluebird all week. We didn't touch hardpack the entire time......just pow.
If you go to Valle, go to the summit and hike. You will get 3000 feet of freshies that will take you back to the road. Just hitchhike back to the resort. Turst me, it is worth it (bring avy gear though).
If you are staying at the resort up at Valle Nevado, bring lots of beer with you because it is really expensive at the resort. Also, if you need to unload gear, bring it ans sell it to the locals, they are a season behind.
