I just got back two days ago from Port Orleans French Quarter. I was sick
the first two days and was in room sleeping with room occupied sign on door. I heard some knocking and ignored it, figuring it was just housekeeping or something. I was surprised when a Disney staffer opened the door--and I think he was surprised to see me...
He explained that he had to do a quick safety check and provided me a card explaining what he was doing. It seemed a little sketchy to me as I was not familiar with this new process, but took five seconds so whatever. Second day, same thing, but this time I get up and answered the door for 'Safety Man'. I asked him what the deal was. He explained that since Las Vegas they have to check every resort room on property every single day.
I'm fine with the whole thing just wish the front desk gave guests a heads up at check in. Though if you look at the fine print on the new 'Room Occupied' signs it basically says, 'whatever but we can enter your room anytime anyway.' I kind of get the whole thing, I mean after Las Vegas there was some much speculation about how the 'hotel could have done more'. Also, my experience this time was that bag check was way more intense and time consuming than it was three years ago when I was there. Then it just seemed like a cursory quick check. This time it was open every pocket, unzip every zipper on the backpack type check. Also on the day we were at Magic Kingdom, everyone guest had to go through metal detector. At Hollywood Studios they seemed to be just selecting every tenth person or so.
Maybe they are just trying to step up security in general. I do think the front desk alerting guests would be helpful though.
