I think you need constant ski lift lines of 20-60 minutes to upsell skiers on line-cutting privileges or Express Pass.
The only semi-equivalent industry I see is the Orlando theme parks (Disney, Universal). I have often gone to Disney or Universal 1-2x per year for conferences to either give a talk or case study, or to meet customers/partners, etc. Most Universal Hotels always came with free Express Passes and 50% off theme park tickets for conference attendees. So I would check out whatever was new, and do everything interesting in 2-4 hours, even when lines were 30-120 minutes throughout the day (12+ Hours) during Spring Breaks, Fall, etc.
However, Ski resorts have such high-capacity lifts that lines are no longer a huge issue. The core lifts with the biggest verticals are not that bad, except for the weekend/holiday mid-morning rush through the afternoons (maybe 15-20 on a few?). You can always find a non-core lift. And North American resorts somewhat overstaff the lift queue management. They want greeters; look up your hometown, maintain/police express lines, and set them up every day. Are they really going to staff all lifts? No, just a few. Most lifts have almost no lines by 2 pm. And Powder Days cannot be obviously predicted, but the locals who create the lines often disappear by 12 noonish.
Theme Parks have longer lines for more hours, so customers are willing to pay.
Currently, parking is a much bigger issue at ski areas than lift lines, and people sometimes have to pay for it.
Northstar sells/sold Express Passes, and the express lines existed on a few front-side lifts from 10 am to 130 pm.
Flims Laax sells Express Passes. I don't think I saw a single skier using one during mid-week March.
Jackson offers all types of camps/private lessons, so in effect, it has a very expensive 'Express Pass' primarily for Tram Access, Gondola, or weekend powder days. Same with Big Sky and its tram—it's called a surcharge.
Some resorts that might be candidates for weekend/holiday Express Passes are: Whistler, Summit County, CO/UT, Vail, Heavenly. Not sure what is even busy, but over the last 10-15 years, I've never had any bad lines at Tremblant, St. Anne, Whiteface, or Gore. Maybe Loon, Okemo, Stowe?
