When I was on the Celebration TA the room steward introduced himself the first day and said he does rooms between 8:00 AM and 4:00 PM. I thought he was asking for my preferred time, so I told him I’m always out of the room by 8:00, thinking that would help him. He said he doesn’t target any specific time for any staterooms, just does them when he gets to them between his stated hours. Never heard that before. Usually the steward are glad to know they have some early birds he can get to first.
