My point about hyperbole is this.
Here's what we know, officially, from Disney: The Do Not Disturb signs are being removed from rooms. A Disney employee will enter the room once per day. Generally, that will be covered by the daily housekeeping visit. You can still choose to decline housekeeping, but in that event, “the hotel and its staff reserve the right to enter your room for any purposes including, but not limited to, performing maintenance and repairs or checking on the safety and security of guests and property.” That statement isn't anything new or radical, by the way. Any hotel you have ever stayed in, or ever will, has the ability and the right to have their staff enter guest rooms when it's deemed necessary by management.
That's it. There has been no mention by Disney of security guards barging into your room at all hours, conducting searches of the room or your possessions. Or cameras in the room, or body searches, or any of the other wild assumptions that have been posted on these threads. Most of what people are reacting to is speculation and worst-case assumptions by their fellow posters. There's just no point to that. It's not helpful, it's not productive, and it sends a thread right off the rails into argument-and-personal-attack territory. Is it possible that Disney is creating their own massive force of armed agents that will be pounding on guests' doors late at night so they can search their room? Well, yeah, I guess. It's also possible that I'll hit Powerball this week and win enough money to buy Disney Springs. Neither are very likely, and I think it's a better use of time and board space to talk about things that might actually happen.
My own assumption: Disney is protecting themselves from the legal exposure that the Mandalay Bay now faces because one of their guests had an arsenal in his room and they didn't know about it because he kept his do not disturb sign up. They're just putting a set of employee eyeballs on the rooms to make sure nothing is obviously amiss.
Most guests will be utterly unaffected by this, because the majority of guests don't decline housekeeping. I suspect that for guests that do decline housekeeping they'll try to have a housekeeper open the door and take a look around, so the housekeeper can check the box on her clipboard that says "Nope, no stacks of ammo on the table." It makes sense to have the housekeepers do the check, because a) they're a friendly, non-intimidating presence, and b) the resort is already staffed to have a housekeeper visit each room each day. To have security guards check each of the 30,000 rooms would require a mass hiring. My guess is that security will only become involved if housekeeping or maintenance sees something suspicious, or a guest is very resistant to allowing staff in the room, or is otherwise behaving in a way that arouses suspicion.
Is it reasonable to have concerns about this? Of course. It will be a concern and an inconvenience for those guests who usually decline housekeeping. My suggestion? Talk to guest services at the resort if you're worried. We all know that Disney will bend over backward to accommodate a guest's needs whenever possible. If you need to rest in your room during the day, tell them. If you're concerned about privacy, tell them. Give the staff the opportunity to help.
If you're worried someone will open the door while you're changing or showering or sleeping.....that's what that flip latch on the door is for. I've never been barged in on in a hotel room, because that latch is always closed if I'm in the room. If housekeeping or maintenance tries to open the door, I just say "Can you come back later, please?" Yes, I know that those latches can be opened by staff. I hardly think they're going to be forcing the door unless they think you're dying on the floor or are about to start shooting out the window.
All hotels struggle with the balance between providing security and providing a good guest experience. A lot of the assumptions I've seen here would create an environment so unpleasant for guests that no one would ever stay at a Disney resort again. I think there's very, very little chance that Disney will willingly put their own resorts out of business.
