no comparison! go to steamboat! even with 1000 kids still great skiing, good mobility around the mountain - only time you will probably see them is in the gondola line, in the morning and if you get up early, i bet you'd miss them. Ski the storm peak lift and you will totally miss them (they will all head to sunshine lift and spend the day there). Not the steeps you might find at Abasin but still, lots of runs with good pucker factor
and a fun town, good mexican at fiesta jalisco, the rio is 'way too crowded but reports are that it does make excellent margaritas.
steamboat doesn't (usually) have the fur and bogner crowd, much nicer (JMHO) atmosphere than front range skiing, lots of events for whole families, good ski school, stay on the mountain - shouldn' t be too expensive this time of year
i'm biased, lived in CO five years and still have a condo in steamboat, which I got after skiing and appraising crowds and traffic patterns (!!!) heading up I-70. Yuck.
have fun, skip vail!!!
