I agree with the suggestions about Vail, not in small part because it will be blacked out from the passes that weekend (as someone else mentioned). That is a REALLY busy time at Breck. Hotel rates will be jacked up (as will lift tickets), but as others have said, the Back Bowls and Blue Sky are great. I stayed at the Apollo once and found that some of the rooms are very dumpy. Maybe my standards are too high, but I think the Tivoli will be much nicer. Be forewarned, however, that they just underwent a major multimillion dollar renovation, so they may be more expensive now. Interesting trivia- the Tivoli is owned by the parents of Buddy Lazier, who won the Indy 500 a couple of years ago.
There are a number of Vail locals here on epic- Ric Reiter (www.vailsnopro.com)
, Bob Barnes, vera, and others who I am sure I am forgetting for the moment- you should email or pm them for additional ideas (and maybe hook up with them to ski with, too!)
