In this age of smart recording devices and pinhole sized drones, always remember when staying in a hotel, that you can use this method to check your room: 1.When you have entered into your room, turn off the lights, and close the curtains Open your phone camera, do not turn the flash light on. 2.Turn around the room with your cellphone.
