The Hampton Inn Bennington is within a reasonabel drive to Stratton, Bromley, and Mount Snow.
As was mentioned, the Hampton Inn Rutland will work for Killington, Pico, Okemo, and Sugarbush.
I'm not a huge fan of either Hampton Inn, as they refuse to even consider a late check-out (even on a Sunday when their occupancy plumets).
I almost forgot that there is also a Hampton in Brattleboro, which is within a drive to Mount Snow and Magic.
