Spring break is later in April. When spring arrives, the locals start golfing and biking and the slopes open up.
I'd recommend staying in the valley. If you like Apres' Ski there are a number of hotels downtown such as the Peery Hotel, Crystal Inn, Hilton, Monaco, Marriot etc, that are right in the middle of the dining scene. From here you can get to Snowbird, Solitude, Brighton, Park City, Canyons, and Snowbasin in 30 - 45 minutes. If you want to stay in the mountains, there are plenty of options.
This time of the season, Snowbird and Solitude (perhaps Park City) also have hotel and pass deals such as room and ticket for $99 per person.
The snow is excellent now with bases averaging near 120". This week's forecast is snow every day. March does tend to be a snowy month. You'll find the most consistent groomers at Solitude and Park City, although the other resorts are splendid.
Pick up discount tickets at the ski rental spots in town such as Canyon Sports or go to Costco as well.
Enjoy.
