He had/has Accor Platinum status, right? Giving his expenditures at Sofitel and the easy access to the status, he should have.

I have never had housekeeping come into my room unexpectedly while in the room, but then again I am pretty "religious" about minimizing the chances of that happening by using the DND sign, the additional lock features, etc.

I have unexpectedly entered the room of individuals or couples who were undressed and/or freshly naked out of the shower; but that was mostly a function of being assigned occupied rooms when showing up for early check-in. Seems to have happened most often to me at Marriott hotels and I've rarely had Gold or Silver status there.
