There is a thread locked to the top of the forums where many people have had CMs walk in on people WITHOUT being let in by guests.
You seem to be saying that such behavior is just fine, and it is the guest's fault for not putting on the security latch, which many others have explained very plainly that does not work if there are other members of your party outside the room.
Does it matter that the CMs have not (yet) been documented to override the latch (which they can do)? They ARE documented walking in without being granted entry by the guest renting the room. You are focusing on a completely irrelevant piece of information.
Since this fiasco started in January, I have stayed at many other hotels. Not a single one has implemented this policy. Most still do have do not disturb signs, and only state that if you leave the sign up for 24 hours in a row they might check in on the room. That's it. That still respects the guests' privacy while providing the security theater that some people believe is needed now (major eyeroll, but whatever).
I find it amazing that there are any guests out there who think it is fine for random male security guards to walk in on sleeping women because it is the women's fault for not engaging the latch and locking the rest of their families out.
