Revenue from Contract with Customer [Abstract]
Revenue [Policy Text Block]	2020/2021 North American Credit Offer and Epic Coverage As a result of the COVID-19 pandemic, the Company closed its North American destination mountain resorts, regional ski areas and retail stores early during the 2019/2020 North American ski season, beginning on March 15, 2020. Subsequently, the Company announced a credit offer for all existing 2019/2020 North American ski season pass product holders to purchase 2020/2021 North American ski season pass products at a discount (the “Credit Offer”). The Credit Offer discounts ranged from a minimum of 20% to a maximum of 80% for season pass holders, depending on the number of days the pass holder used their pass product during the 2019/2020 season and a credit, with no minimum, but up to 80% for multi-day pass products, such as the Epic Day Pass, based on total unused days. The Credit Offer was considered a contract modification which constituted a material right to 2019/2020 North American ski season guests and, as such, represents a separate performance obligation to which the Company allocated a transaction price of approximately $120.9 million. As a result, the Company deferred $120.9 million of pass product revenue, which would have otherwise been recognized as lift revenue during the year ended July 31, 2020. The Credit Offer expired on September 17, 2020 and the Company estimates the amount of Credit Offer discounts redeemed will be approximately $15.4 million less than the $120.9 million of deferred pass product revenue. As a result, the Company recognized $15.4 million as lift revenue during the three months ended October 31, 2020. The remaining deferred revenue associated with the Credit Offer will be recognized as lift revenue as the performance obligations are satisfied, which the Company expects will be primarily in the second and third quarters of the fiscal year ending July 31, 2021. In the event that a pass product holder obtains a refund under Epic Coverage (as discussed below) for the 2020/2021 North American ski season and is eligible to utilize their credit toward the purchase of a pass product purchase for the 2021/2022 North American ski season, a portion of this remaining deferred revenue will be recognized in the year ending July 31, 2022. In April 2020, the Company announced Epic Coverage, which is included with the purchase of all 2020/2021 North American pass products for no additional charge. Epic Coverage offers refunds to 2020/2021 North American pass product holders if certain qualifying personal or resort closure events occur before or during the 2020/2021 North American ski season, as well as in the event that the pass product holder cannot reserve their preferred days between December 8, 2020 and April 4, 2021, and the amount of expected refunds will reduce the amount of pass product revenue recognized during the year ending July 31, 2021. To estimate the amount of refunds under Epic Coverage, the Company considered historical claims data for personal events, current travel restrictions (primarily associated with travel into Canada from the United States and other countries), state, county and local regulations (e.g. quarantines and stay-at-home orders), the ability for the Company’s pass holders to make reservations on their preferred days, and the Company’s current operating plans for its resorts. The Company believes the estimates of refunds are reasonable; however, actual results could vary materially from such estimates, and such estimates will be remeasured at each reporting date. Additionally, for the 2020/2021 North American ski season, the Company introduced Epic Mountain Rewards, a program which provides pass product holders a discount of 20% off on-mountain food and beverage, lodging, group ski and ride school lessons, equipment rentals and more at the Company's North American owned and operated Resorts. Epic Mountain Rewards constitutes a material right to pass product holders and as a result, the Company will allocate a portion of the transaction price based on the standalone selling price of the customer option to acquire additional goods or services at a discount and the expected redemption rate.
