It's not supposed to be mandatory. I don't know what it any checking is taking place but I'd be surprised if ghey are. Maybe when they check that you've registered to be there they might ask. Previously when it was "recommended", there was no checkingJust read this also, seems it is no longer compulsory to have a negative test if you are regional
'If visiting an Alpine resort, it is strongly recommended that you have a COVID-19 test performed and receive a negative result within 72 hours of entering the resort.'
Is the recommendation being enforced as mandatory?
