This thread is gold--exactly the info I needed!
My thoughts so far, based on everything I've read:
1.) I'm for sure getting a rental car now--I want the flexibility to follow the snow/see what's around.
2.) I like the idea of staying in PC since we're realistically going to ski in that area the majority of our time.
3.) Holy crap, lodging is so much cheaper than in CO! Wow... easy to find stuff for under $100 a night from my research so far. And yes, our priority isn't super awesome accommodations, it's the skiing! :)
