Indeed, it's primarily in nicer, international standard hotels that I've had to deal with fussy controls such as key-operated lights, motion-sensitive HVAC (that shuts off while you're asleep leaving you to awaken 2 hours later sweating or shivering), and shining, flashing status LEDs everywhere. Last time I crashed in a flophouse with a mural of a naked woman in the shower and a lotion dispenser mounted on the wall next to the bed, I had none of those annoyances, just good old-fashioned wall switches to control the mood lighting overhead and a heater that gurgled steadily throughout the night. I got to sleep easily that night. The prostitute working the floor even honored my "Do Not Disturb" sign and didn't so much as knock.
