Good call dude. Burlington is a good choice becuase you have options. Plus, Killington is just retarded on President's Day Weekend. You'll be left wondering whether you are paying to ski or wait in line with a bunch of rear-entry suckas from NYC. In Burlington, you won't necessarilly be able to do apres-ski on the hill, but the bar scene up there makes up for it (Red Square is a favorite). Plus your non-skiing buds will have plenty to do. Go to Stowe if you must, Sugarbush if you want, and Jay because you have to. I know I am starting to sound like a broken record, but riding in the East does not get better than Jay Peak. Well except for a prime day up at Tucky's, but that is it.
If there is snow in the trees, I highly recommend doing the "Dip" at Jay. Enter the Timbuktu woods, stay high on the track, head out past the boundary. If you drop straight off from the track or to skiers left a little you will end up at a road that will allow you to hitch back to the resort. Don't stray too far to skiers right in there, you'll end up in a basin off the road.
