which one of these is not a physical security feature you should check when inspecting your hotel room?

The physical security feature you should NOT check when inspecting your hotel room is the "proximity of the room to emergency exits." While proximity to emergency exits is important for safety and emergency preparedness, it is not a physical security feature of the room itself. Physical security features include the solidity of the door, functioning locks on doors and windows, and the presence of a lockbox or safe for securing valuables. Therefore, the proximity to emergency exits pertains more to emergency escape plans rather than the immediate physical security features of the hotel room.
