If you’ve visited a Walt Disney World hotel recently, you may have noticed that the traditional “Do not disturb” signs have been replaced with “Room Occupied” signs.

The gunman kept a “Do not disturb” sign on his door for days before the attack as he stockpiled weaponry, so hotel staff didn’t enter the room, according to news reports.

Walt Disney World has swapped 'Do Not Disturb' signs with "Room Occupied" and will check rooms on a daily basis. Hilton, Boyd Gaming and Wynn Las Vegas have also changed their DND policies.
