Not true in our case. We were napping in the afternoon, after requesting at the front desk that housekeeping come between 7:30am and 12:30pm. We have medical reasons for that request; however, the REASON should not matter. It is vacation.
Anyway, my husband fell asleep and I got up to the knocking, at about 2:30pm. I told housekeeping that we were napping and would like her to come back after 4pm when we would be gone. She was not happy with that but left. About 15 minutes later, another knock on the door. My husband answered and security wanted to come in. By that point, we were awake so he told him to come back in 15 min. and we would be gone. Frustrating!
The question is: was security alerted by housekeeping just because we wanted them to wait for one and a half hours so we could get our needed rest? Seems like it is NOT a coincidence to me. BTW the room occupied sign was on the door, too.
