Effective December 22, 2017, Walt Disney World has a new security procedure beginning with Grand Floridian, Polynesian and Contemporary Resorts.
Walt Disney World Resorts will no longer provide guests with “Do Not Disturb” signs to put on their doors. The signs will be replaced with “Room Occupied” signs that will notify cast members that guests are in the rooms. Guests could still be “disturbed”, though, while in their room. A Disney cast member is required to enter the hotel room at least once a day to ensure guest safety.
You can still choose to skip mousekeeping. Disney states that “the hotel and its staff reserve the right to enter your room, even when this sign is displayed, for maintenance, safety, security or any other purpose." See the pictures of the sign above. Disney cast members knock and announce their presence before entering.
There's great speculation as to why this change is being made, but bottom line is, it's a different world now and certain security measures are necessary to protect guests and cast members. Some Disney resorts are quite tall and have viewable access to crowded guest areas including Walt Disney World transportation. Disney has not stated a reason for this change.
These changes are expected to roll out to other Walt Disney World Resorts in the coming weeks.
