I've heard about this and seen some offers in the past, but was looking for a little more comprehensive list of which major ski resorts offer a specially priced season pass just for the spring portion of the season? Asking about this year, but also with next year 2015 in mind.
Snowbird, UT: Mar 1, 2014 to closing (May?) = $499, Apr 1 to closing = $329
Arapahoe Basin, CO: now until closing (May?) = $179, now until closing and good all next season = $279 (A-Basin only). Not sure when "now" started, anybody know?
Mt. Bachelor, OR, Mar 31 to closing (late May) = $179
Killington, VT: mid-March to closing = $179
Pretty sure several other resorts do this annually, but may wait until around the first of April to announce?? Squaw, Winter Park, Steamboat?
