I travel for work all the time and stay in a LOT of hotels. If you put your "Do not disturb" sign on the door, they won't come in, period. I even know people who do this as a matter of course and never have maid service when they stay at hotels.
Vegas would be devoid of life if all the FFLs started using their equipment outside their hotel room during the SHOT show...but liberals want you to believe its the guns fault.
