Just back from 5 days at POR. We had housekeeping daily. When in room we used the bolt and extra latch and put out the room occupied sign. At night I put an extra note on the door that said still sleeping please come back later. Never bothered by housekeeping or security checks. Typical schedule was in room til 10 or 10:30 AM... back and forth from pool all day, then out at parks for rest of evening by 5pm.
