That's what happens on threads. Especially ones where the OP isn't still active.
Nothing that they do now would have stopped the Vegas guy. Nothing TSA does now that they didn't do then would have stopped 9/11. Theater. The real stuff can be done without the theater.
See my post about my ex and work travels. He traveled with a ton of weird electronics, some of which were prototypes. His job was on the line to keep those secret. His now-former company doesn't play the games Apple plays where they "accidentally" leave things out.
I don't want to have to put my bras away just to feel comfy that someone might enter the room. I dislike having housekeeping come in. Especially since my WDW stays since 2016 haven't involved park days other than two free
DVC parties, I'm in and out of my room a lot, and hate to have to clean up so I'm OK with someone coming in to clean.
As I posted much earlier in the thread, Disney housekeeping is known for parking the cart in front of one open room and going to the next room to clean with the door closed. Anyone small enough to scoot by the cart or strong enough to move the cart can enter that open room that the housekeeper isn't in. Sometimes they get caught (my then-husband did when he went back to the room at Grand Californian to get something for me) but usually they don't. It's a gaping hole in room security.
As I mentioned in your other post, Disney is known to do the sorting behind the scenes.
