I enjoyed smuggler's notch when I was there. Its a little bit easier on the wallet and the conditions seem to stay better longer than some of the other mountains in Vermont. The biggest draw back are the chair lifts. They are only two seaters and are painfully slow, averaging about 15 minutes to the top... That said, they extend for what seems like miles up into the clouds and you do get to spend a fair amount of time on the way down. Snow is great and well groomed, the glades are not as good as Stow or some parts of Killington, but they are still fun.
I'm not sure how good it would be for families as you would indeed need to split up to make it up the lift lines. I believe they have a good instructional program though if you just want to dump the kids off somewhere.
