Attorney Daniel Tarpey expects it to be an “arduous” and “long procedural fight.” He and co-counsel have to prove there are enough skiers that may have been harmed in the same way during Park City Mountain’s recent strike to justify class action.

Skiers have filed a class action lawsuit against Vail Resorts, saying they spent thousands of dollars to visit Park City Mountain and Vail Resorts didn’t disclose an ongoing strike or its impacts.

Ski patrollers at the biggest U.S. ski resort reached a tentative deal with the corporate owner of Utah’s Park City Mountain Resort to end a strike and resume normal operations after almost two weeks of closed terrain and long lift lines at the busiest time of year.
