Are you driving or flying? If flying, the best advice we ever received for Spring Break Skiing is Jackson Hole. Everyone driving sticks to Colorado/Utah/NM and they are stuffed with people. Jackson was not crowded at SB in any way. The instructors are incredible. No one in our family had skied before, but by the end of the second day they had us on some easy blues and feeling pretty good about it. Everyone goes to Jackson for the big stuff (Corbet's etc) up top, so the greens and blues were wide open and really fun. As a novice family, we had a great experience there. We stayed in town, had a ton of restaurants and shops to walk to and then shuttled to the slopes. If you don't want to ski the whole time, we did a snow shoe guided hike in the Tetons and took a snow cat out to Yellowstone for a couple of days to recover from skiing . We had Old Faithful literary to ourselves at the end of the day.
