The best hotel hacks don’t require a key card to turn on the lights
Many hotels have done everything they can to minimize their carbon footprint. This has been achieved in many ways. For example, several hotels have implemented the idea that electricity will only work if the keycard is inserted in a specific slot. It’s great, until you forget your key card.
We may also need to charge things or lend our card to another person in the room, and we don’t want the electricity to be cut off. Hotel hacks have shown that any card will work in the slot. No more key cards to forget.
