I’d pass on Stratton as it is very expensive, can be crowded and an overall poor experience. It’s more of a gondola and pumpkin latte crowd than a quality skiing experience. For a beginner looking for cruising terrain I’d give Okemo, Bretton Woods and Bromley a shot.
For an experienced skier looking for terrain, when there is quality natural snow there is nothing better on the east coast than Magic Mtn.
