Leaving two cups on your hotel room door handle may seem trivial, but it can provide an important layer of security. Travelers staying overnight in hotels or guesthouses should be aware of this simple safety trick to protect themselves.

You will need two cups (either brought from home or provided by the hotel). At night, before going to sleep, place one cup horizontally across the door handle and the other upright on top of it. Additionally, place a heavy object such as a chair or suitcase against the bottom of the door to further block entry.

Why does this work?

This setup acts as an alert system against intruders. If someone tries to open the door from the outside, the cups will fall, producing a loud noise that can wake you instantly. The sound may also startle the intruder, causing them to abandon their attempt. Meanwhile, the chair or suitcase obstructs the door, giving you time to react and secure yourself.

Checking Under the Bed: Why Throwing a Water Bottle Helps

When entering a hotel room, it’s important to inspect hidden areas for safety. One simple method is tossing a water bottle under the bed.

If the bottle does not roll freely, it could indicate an obstruction or even someone hiding. You can then investigate yourself or ask a travel companion or hotel staff to assist. If no one is there, the bottle will roll freely, confirming the area is clear.

This practice also helps you evaluate the room’s cleanliness. Under the bed may hide dust, hair, leftover trash, or even forgotten items from previous guests. In some cases, it can harbor insects such as ants, cockroaches, or other pests that can affect your health. There is also a risk of valuable items or dangerous objects being left behind. A quick check under the bed can prevent potential accidents or security issues.

Other Safety Tips When Staying in a Hotel

1. Cover the Peephole:
   For doors with a peephole, place tape or a sticker over it to prevent anyone from looking in, or to block hidden cameras. You can easily remove the tape whenever you want to use the peephole.

2. Use the “Do Not Disturb” Sign:
   Hanging a “Do Not Disturb” sign on your door discourages unwanted entry while you are inside or away from the room.

3. Check for Hidden Cameras or Listening Devices:
   Upon entering your room, carefully inspect unusual places such as picture frames, mirrors, electronic devices, or vents for hidden cameras or recording devices.

4. Secure Your Belongings:
   Store valuables in the hotel safe when available, and keep luggage locked to reduce the risk of theft.

5. Stay Alert at All Times:
   Even small actions like placing cups on the door or checking under the bed can significantly improve your personal safety. These precautions may only take a few seconds but can prevent serious incidents.

By combining these simple methods, you can significantly reduce risks when staying alone in a hotel. A few small precautions can provide peace of mind and keep your stay safe and comfortable.
