no crowds at advanced terrain; beautiful tree runs when back bowls are open
crowds at popular blue slopes; expensive food
I went there for a week in JAN 2012, and all I want to say - it's fantastic resort. Plenty of groomed slopes as well as moguls runs. When back bowls are open the resort has the greatest ski area in US. It takes about an hour to get from furthest place to lodge.
I got a season pass for all Vail Inc mountains, so I didn't care that lift price is over $100.
The crowds tend to be on the nice blue runs lifts.
