Make Your Own Humidifier
No humidifier? No problem! Tackle dry hotel room air with this ingenious hack: utilize the built-in air conditioning unit as a makeshift humidifier. Simply grab a damp towel and secure it over the luggage rack near the A/C. For continuous humidification throughout the night, keep one end of the towel soaked in a bucket of water. Rest easy with the perfect balance of moisture in your room.
