There are a number of Hyatt's and Marriott's including CO and Utah, St. James is another great resort. I can come up with a better list from resort quality once I'm home though we don't ski, but you can likely bet better info from TUG. If you go to TUG (tug2.net) don't confuse them with
DVC, just either list the resorts you're considering or ask for the better II resorts. Early Dec and Jan won't be too bad if you search at least a year out, Xmas and late Feb through March will be almost impossible to get.
