Welcome AJF. Check out the DCSKI Q&A section. See comments about fave places to ski outside local area. Some of my distant trip choices are determined by catching a good airfare, esp if I'm bringing all or good part of my family of six with me. All things being equal, it is hard to beat SLC for price and convenience once on the ground, esp if you stay in SLC suburbs and commute to affordable places like Alta, Brighton, etc.
Lots of fine choices in CO, which this winter featured some of the best fares from our local airports to Denver. Some folks find relative bargains staying at Breckenridge, Copper, Winter Park. Sometimes there are good fares to northern CA too. Lots of cheap motels very close to Heavenly in South Lake Tahoe, and some around north end of Lake Tahoe too or find bargains commuting from Reno. Travel early or late, of course, will also offer good prices. This was a very fun trip, despite a tight family budget:http://184.108.40.206/articles/view_article.php?article_id=281&mode=headlines
