The newer units are in West Hill (Sycamores and Falcons), North Hill (Tamaracks and Eagles) and Highlands (Aspens). The buildings that are named for birds- like Falcons, Kestrels are family share buildings and bit more upper end and the Owls have the Presidential suites.There are also some very nice units in the village, but then there are also older units there as well. The resort has been slowly upgrading many of them, so I wouldn't count them out entirely. The Willows, which are also just outside the village are very nice.
Besides being newer construction, the difference is that West Hill, North Hill and Highlands have use of their own pool and the village homes use the "bubble enclosed" (in fall and winter) Courtside pool and hot tubs. Also, Mountain Laurels (in Highlands area) have their own pool. I believe it is a salt water pool.The Aspens and Sycamores pools are heated and, although outside, open all year round. North Hill has an indoor and outdoor pool. They each have a small clubhouse and gym/lockers.
The best time to go in the Fall is by Columbus Day week the latest. Anytime past that week, the foliage is brown and going, and it gets cold, and the other issue is the Notch closes soon afterward and you can't drive through it (an experience in itself-something not to miss) and you have to drive the longer way into Stowe, which you would want to visit, as there are good restaurants, shops, and things to see like Mount Mansfield (take the auto toll road or the gondola) and Trapp Family Lodge among others.
