Okay, here's my read on Priority Reservation vs. Core Season coverage:
- If you have a particular period of up to a week that you intend to do all your skiing for the season in, and you don't intend to ski at any other point, Priority Reservation coverage is likely the way to go, since it provides you with a proportional refund for any PR day you lose.
- Example: I have a five-day pass, select PR coverage, and book a full week of skiing with my PR days. Three of those days are cancelled; I sip hot cocoa in the cabin and receive a 60% refund on my pass.
- If you have a particular period of up to a week that you intend to do most of your skiing in, but you also plan to ski other days as you can make time for them, PR coverage might still be the way to go. However, selecting PR coverage penalizes you disproportionately if you ski days that aren't PR days by reducing your potential refund if you lose PR days due to resort closures by some amount that increases with the number of non-PR days you ski.
- Example: I have an unlimited pass, select PR coverage, and book a seven-day trip using PR days. Two of those days are cancelled, but I go on a day trip later in the season. I receive a 14% refund on my pass, which is less than the 28% refund I would've received if I hadn't gone for that additional day trip.
- If you plan on skiing regularly (seven days or more a year) and aren't tied to a particular set of dates, PR coverage is a bad idea, since it'll likely end up with you getting no refund at all. If you have an unlimited pass and ski seven or more days, or a pass with a limited number of days and use them all, you won't receive any refund using PR coverage even if none of your PR days are available.
- Example: I have an unlimited pass, select PR coverage, and book a seven-day trip using PR days. COVID shuts down the resort for a whole month surrounding my booking. However, later in the season, I manage to do a bunch of day trips and weekends, and end up skiing 15 days. I receive no refund, even though I didn't get any of my PR days.
This setup is definitely designed to be confusing, and it's not even that they don't want you to figure out what the "good option" is—it seems to be designed to hide the fact that there really isn't a "good option" at all.
I'm personally going with Core Season coverage with Northstar as my Primary Resort.
One thing to note about the Core Season/Primary Resort configuration is that skiing at another resort on a day when your Primary Resort is closed will penalize your potential for a refund in a way similar to the way doing unplanned day trips when Priority Reservation coverage is selected will. If Northstar is closed for a month (out of a 120-day season), then if I don't ski anywhere else during that month, I'll get about a 25% refund. But if I ski just two days out of that month at another resort, then my refund is completely eliminated.
I do think that if you select Core Season coverage, it's strictly-speaking better to pick a particular resort than it is to go with the "All Resorts" coverage. The "All Resorts" coverage essentially only will yield a refund if none of the resorts on your pass are open, and the refund potential isn't any greater than if you pick one particular resort you're likely to frequent.
