Many hotels are built in this way with an access corridor down the middle. This is what has lead to so many invasion of privacy issues among hotel chains in where maintenance personnel would create viewing ports behind mirrors by scratching the silver away from the glass or small holes in the wall paper patterns . A sign that this was happening was notably a pile of cigarette butts and bottle caps on the floor in a corridor where the voyeurs would stand for hours after work watching their victims. Under close examination some form of viewing port would be found near this evidence along with the DNA of the criminal.
SICK!
