A class action lawsuit has been filed against Vail Resorts by an Illinois man, alleging that skiers were not informed about a strike at Park City Mountain Resort prior to making bookings. The lawsuit claims that customers spent tens of thousands of dollars for a vacation that turned into a 'colossal nightmare.' The suit highlights complaints from customers who faced long wait times in lift lines during the holiday season, despite having paid premium prices. These issues have led to growing frustration among skiers, overshadowing previous positive experiences attributed to heavy snowfall.
