Not sure how it Works now but when we were Sleeping off Nights at Brize in the 80"s during an Inspection we used to put a Sign on the Door "Sleeping Off Nights" and then we weren"t Disturbed.
Most of us had Single Rooms by the Late 80"s though opposite Gate 1 not far from the Chinkie.
And we were allowed a Microwave to Heat it up in the Morning for Breakfast.
