modern hotel thermostats are, in a word, a pain. Well over a decade ago, we noticed the kind of thermostat where you were supposed to put your room key into a slot to keep the air conditioning (and sometimes the electricity!) running, which meant when you were out of the room, your A/C wouldn’t run and when you got back, the room would be uncomfortable. That one was easy to override because just about ANY card worked in the slot ;-).

As modern technology got more advanced, they started building motion sensors into hotel thermostats, which meant that not only did you have to be in the room for the A/C to work, you had to be moving around…so if you were sleeping and woke up in the middle of the night, the room could be uncomfortable because unless they were sleepwalking, no one had moved around in several hours.

And then there are the thermostats with upper or lower limits that you can’t bypass so the room won’t get warmer or colder than the hotel wants. Oh great, that way we can be uncomfortable in our room while we’re wide awake, too!

Fortunately, electronic-savvy travelers have made it their business to figure out how to override these nuisance thermostats so we can be in our hotel rooms more comfortably. Here are some hacks we’ve found (only found; we haven’t “invented” any) for some of the most popular brands at some of the more popular hotels:

NOTE #1: Of course, the hotels don’t want you to mess with their thermostats. Besides potentially using up more energy than the hotel intended, you run the risk of breaking their thermostat, like these people did – and frankly, the hotel may or may not hold you responsible for the repair bill. Your Mileage May Vary as to whether it’s a good idea or not to try to bypass the controls set by the hotel – but if you think it’s OK, here are some ways to do it.
