Ski and ride six premier resorts – Killington, Sunday River, Mount Snow, Attitash, Sugarloaf/USA and Pico – all season long for one low price. Starting at only $395, it pays for itself after just 6 visits.

From my experience last year I have concluded it's better to have a pass than paying for lifts everyday you visit them.
