That late in the season you may want to watch the weather and stay somewhere like either Burlington or Waterbury. From these places you can pretty easily hit Sugarbush, Stowe, or Jay - and maybe mix it up between a few places on different days. If you stay in Burlington and the snow is really bad for whatever reason at least you would have other stuff to do (skate, go to Burton, movies, Church Street, good food, etc.) Most resorts in Vermont will try to make until Easter, but the northern resorts tend to hold up better in the late season. Getting a room should not be a problem so you could even book last minute and see who has the best conditions for you (Mount Snow may have the best park that weekend, but 12" of random pow at Jay or Stowe is pretty common even in mid-April). Have fun.
