That is incorrect. They absolutely know whether you've accessed the room yet. Until you use the key to open the door, you are not really checked-in. If you never open the door, you will be marked as a no-show and will earn nothing. That's why you can't mattress run remote; you must physically access the room. Correspondingly, until you've accessed the room, you are absolutely subject to a potential downgrade. Is it a low thing for a property to do? Yes. Can it be done? Yes.
