I don't think there are going to be a lot of day trippers regardless of the quarantine situation. First of all, day passes will be limited and require advance purchase. That eliminates a big segment of the day tripper population. I doubt there will be any bus trips at all. Can't imagine any school or organization dealing with a ski trip when they have their hands full otherwise. and groups looking to party more than ski won't be booking trips if the lodges/bars are closed. Maybe i'm wrong (caveat-I thought this thing would be under control by now), but I think its going to be passholders skiing for the most part.
