Vail has never sold a resort, and they just pumped a bunch of money into several legacy Peak resorts that many thought would be sold off. While I expected Mount Snow to eventually get new lifts from Vail, I did not expect Attitash, Jack Frost, or Big Boulder to. They have also restored some of the operating hours they cut over the past two seasons, and are reinstating summer operations at Attitash, which haven't happened since the acquisition.
Attitash in particular had suffered years of neglect under Peak Resorts, and before them ASC. They were held back from reaching their full potential by one lift, the Summit Triple. It was perhaps the most hated lift in the Northeast, a 6200 foot fixed grip that took 15 minutes to ride, and that was their main lift. That's getting replaced in 2023, which will hopefully get them the skier visits they deserve.
