Woodstock and the Woodstock Inn are quintessential Vermont. I was there last week and it was fully decorated for Christmas. People also rave about the Jackson but I haven't stayed there.
South Manchester is also nice. the Equinox is pretty decent. I'd look for a high end Inn or B&B though.
Stowe is a cute town. The ski resort is a few miles outside town. If you like the Sound of Music the Von Trapp Lodge is fun, although not totally luxurious (it needs an upgrade IMO).
Consider Shelbourne farms! It's a working farm on a former Vanderbilt property, but also has a fancy inn right on Lake Champlain. The food there is delicious and the place is within easy range of Stowe, Burlington, Woodstock and all those areas.
Any suggestions for a spring or fall Vermont trip- a beautiful scenic town and fancy hotel or resort? Doesn’t need to be Four Seasons or anything on that level but worth going to. Not going to ski!
