Booking a hotel or motel room for a trip, vacation, or work stay has become a common part of life. However, one important thing to always prioritize is your safety in unfamiliar places.

Why should you toss a bottle of water under the bed right after you check in?

Once you’ve checked in, doing a thorough room inspection can help prevent any unpleasant surprises. Most people inspect the main areas, including the bathroom and closet, to ensure everything is in order and there are no suspicious devices, like hidden cameras. However, not everyone thinks to check under the bed, which can pose potential risks.

Esther, a seasoned flight attendant from KLM Airlines in Holland, has a unique tip. Every time she checks into a hotel room, she tosses a water bottle under the bed as a precaution. If the bottle rolls freely from one side to the other, it’s a good sign that nothing is obstructing the space beneath.
