Smuggs sells itself as a family destination. They seem to have a lot of different programs for kids, both on and off the slopes. I don't have any kids, so I can't pass along any personal experience. As for the skiing, they've got some really good terrain. There's a good variety, from really, really easy greens to some wild steeps and glades. The downside is the lift system. They still have a number of old, slow lifts, some of which are prone to closure due to wind. Weekend lines can get long. As for lodging and dining, the resort itself has several condo developments and some restaurants. Outside the resort, there are some inns and B&Bs in Jeffersonville and Cambridge.
Stowe is one of my favorite places in the East. There's great terrain both on Mt. Mansfield and Spruce Peak. Spruce now has some upgraded lifts, and they're currently constructing a base village. Most of the trails on Spruce are solid blues, with a separate beginner area. Over on Mt. Mansfield, there are 3 distinct areas -- the main mountain, the gondola area, and the Toll House area. The Toll House area is pretty much beginners only -- it's nearly flat. The Gondola serves mostly intermediate cruisers, with some <> and <><> thrown in as well. The main part of the mountain is serviced by a Quad, a Triple, and a Double. This is the home of the famous "Front Four" trails -- Goat, Starr, National, and Liftline. There's good cruising here too.
As for lodging and dining, you've got a wide variety, starting about a mile south of the village, and running up the mountain road almost to the ski area. It all depends on your price range.
Keep in mind that Rt108 from Stowe to Smuggs is CLOSED from November until mid-April or so. This considerably lengthens the drive between the 2 places as compared to summer.
