"I checked in to a room and within an hour, another guest walked into my room with card access. When I addressed this with staff, they blamed the previous guest for not turning in their key when they requested a room change. I was told their policy was the guest would leave their key in the room when they leave which I find to not be appropriate since they more placed responsibility on the previous guest.
There are several opportunities in which the key can be deactivated including when I actually check into the room. I felt blaming the other guest of this mistake and placing responsibility on the previous guest was unprofessional with a lack of care regarding guest safety and I strongly recommend a change in protocol."
