I went to the Vail Marriott on points more that once. It's a great place, but you had better book early! Great dining there as well! Flew into Eagle and took the shuttle, avoiding Denver Airport, and it was worth it! Here's the room and the view from the room, as well as other pictures. Very good staff, and ski rental on property.
In addition to Vail, we have a number of brands in Park City, Utah where you can use points. And I believe (although I'm not 100% positive) that both MVC locations in Park City are "ski in, ski out". Good luck!
