They are checking for human trafficking with these checks, no matter what they call them. WDW would be a good place to hide kids like that, according to what I read about this and Disney. I suspect they are still doing these checks for this reason.

Friends that worked at Disney confirmed this to me.
I had heard it was because of the Las Vegas shooting and it was to check for firearms or other dangerous objects.
Anyone who brings along those types of objects are not leaving them out for CMs to see. Given CMs are not supposed to touch anything of the guests they wouldn't see it. AND Las Vegas was a person in a room with a great vantage point ... not sure why any Disney Value or even Moderate resort would have a vantage point. Their "advantage" is lower priced rooms in a prime location.
Objectively, that's understandable, but I guess if trafficking was the concern, I don't know why the checks have to be daily and how checking the rooms when guests aren't in it would address that.
They are trained to look for specific items that look out of place for the guests registered in to the room. They could then report back what objects they saw that would trigger more checks.
It is not a mistake that many guests get checks while they are in the room, because they are putting eyes on guests, part of their check. I agree with you that once should be enough for any guests, but the randomness is to potentially catch something.
Regardless of the concern(s), I am at a loss as to what all of he surface touching by staff has to do with it. I don't love it regardless, and it's not something I've encountered at any other hotel I've stayed at, but it would bother me a lot less if they just would just look around without touching.
It is weird for sure as are the dumb excuses like "checking your fridge" "checking your air vents" "checking the tub" etc. I think they just came up with a script because they need an excuse for what they are doing because what they are doing makes no sense on the surface ESPECIALLY since no other hotels are doing this.
I agree. We stayed at Universal last November and we did not have any "room checks" at all. I wonder if only certain parks are doing this? I've never seen it at Universal before, and have never heard of it from friends who stay at Universal a lot.
When Disney started all this I was actually getting letters in my Hilton rooms stating they would not be doing room inspections like other hotels and for us to enjoy our stay. Have experienced it no where else.
I actually stopped staying on property after some bad experiences with this. I have never let them in the room. I had a trip (last straw) when I was followed to my room. They expected me to open the door which I told them I would not do and told them to use their key. I waited outside for them to do the light switching, tub exploration. When I finally did return I spoke to the front desk about it, that I would not be letting them in with myself and child there so we needed to figure out a block of time I would be gone. It worked out. Last couple times no issues but we are gone most the day. If they should come knocking on my door I would ask them to wait until I got my son's shoes on and we would exit the room shutting the door behind us. They can use their master key to enter the room. I have no assurance they are actually CMs asking to come inside my room.
Fortunately my last few onsite trips we've had no issues.
