There are several reasons for businesses closing or operating restricted hours in resorts at the moment.
Infection rates have rocketed over the last week in many resorts - almost a 6-fold increase in some resorts in just a few days. Most of those infected seem to be hotel staff and ski instructors, who have contact with numerous people during the course of a day and who live in close proximity to one another, often in shared rooms. The net result is that as staff have to quarantine, there are too few staff to cook and serve meals, clean the rooms etc. There was already a general shortage of seasonal staff in many places and some restaurants and hotels have not opened at all.
New Year has been busy in the resorts, but now that the families have gone home the groups that traditionally come in January do not seem to be coming. If they come as much for the party and beer as for the skiing, then clearly the impact of there being no apres ski and the restaurants closing at 22.00 makes that type of holiday less attractive.
For those resorts that are popular with guests from UK, Denmark, Norway and Netherlands, the vaccination and PCR requirements for these guests have had a clear negative effect on bookings.
And so the spiral begins. With fewer staff and fewer customers, some businesses are closing or consolidating. Many hotels, bars and shops are family-owned and they often run 2 or 3 businesses, so by putting all of the guests into one hotel rather than in 3, by opening only one restaurant rather than 3 or 4, or by opening only one ski shop instead of 2 or 3, they can keep the businesses ticking over in the hope that they get a good February.
