Thanks. That is is line with what I found so far. I called the hotel yesterday to verify one point (is an antigen test performed in front of a receptionist acceptable ?) and they were quite in the dark, they say they received nothing yet official about what they can accept and do. Outdoor dining but maybe some sort of things could be offer in the Executive Lounge (I will be in Hilton Munich Park).
I will report after the week-end.
