Beauty is in the eye of the beholder, after all....
and with the airplanes offering less flights, and the time changes,
we prefer later...
I agree it would be nice to be able to flip over the do not disturb sign, to a ready for cleaning, so housekeeping knows when to clean the room.
Generally speaking, we do sleep in, and don't appreciate housekeeping pounding on the door 8 a.m. every hour, to see if the room is ready for them to clean.
