Depending on whether you're toting along the kids, if not, I would recommend shopping airfare to SLC and stay at the Comport Inn Suites in Midvale, UT (at the entrance to the canyon roads) and ski in the little and big cottonwood canyons. I can usually find airfare for $280-325 and a room at the Comfort Inn for $85 per night including breakfast and a big discount on lift tickets. You can take a shuttle bus to Alta / Snowbird (they usually go up even when the canyon road is closed to cars) and I would recommend demoing skis and rent poles, just bring your boots. Book the red-eye home so you can ski the last day and then head for the airport. No need for a rental car, you can get a shuttle from the airport to the hotal and lots of resturants within walking distance in Midvale/Fort Union/Sandy area. SLC always has vacant hotel space since the big build-up for the olympics and rooms are always cheap.
