This isn’t specific to your resorts, but I suspect all resorts will be making similar decisions this season.
I’ve been an Epic (Vail Resorts) pass holder for many years, but I'm waiting until the deadline this year (9/7/20 for full benefits, but I may wait longer) before purchasing another. Meanwhile, I'm monitoring news about how the resorts plan to manage their operations for 2020/2021 (mainly by reading stories on vaildaily.com).
Vail Resorts hasn't said much about the upcoming season yet other than that they are planning to hire full staffs and open all terrain. The Colorado resorts are in discussions with the state of Colorado to see if they can come to some agreement about how to handle COVID. Presumably the issues include capacity, social distancing and limiting liability.
Vail also owns three resorts in Australia that have been operating during our summer with COVID restrictions. These resorts have periodically closed during local outbreaks, and during early season they restricted the total number of skiers on the mountain by requiring advanced reservations in addition to lift tickets/passes. During those restricted days, customers with passes received priority over customers who wanted to purchase daily tickets. Social distancing rules allowed related parties to board lifts normally, but for unrelated parties only one person was allowed on any chairlift with a capacity of three or fewer. Four-person or six-person chairs allowed only two unrelated skiers to board. You can imagine what this would do to lift lines if the overall capacity of the resort wasn't also restricted.
Here are my conclusions for the upcoming season:
1. If there are capacity restrictions, skiers with season passes will likely have priority over non-pass skiers.
2. Don't bother trying to ski on weekends or holidays - either the lift lines will be extremely long, or reservations will be impossible to get.
3. Ski with a group if possible, as the lift lines may allow efficiently sized groups to go to the front of the line.
4. Choose resorts based on their ability to move skiers up the hill despite social distancing requirements. One resort that will probably have problems with this is Vail Mountain, which moves the majority of its skiers from the two base areas using two gondolas. If those gondolas are limited to one unrelated skier each instead of their normal capacity of 6-8, the lift lines at the base will be a nightmare (but lines may be short on the rest of the mountain due to the logjam at the base, so maybe arriving for first chair and avoiding the base areas for the rest of the day will be the winning strategy).
