Few travelers know this clever — and potentially life-saving — hotel hack.
Whenever you check into a hotel or motel, tossing a bottle of water under the bed could be one of the smartest things you do.
Here’s why.
When staying in an unfamiliar place, your first instinct is often to inspect the bathroom, look for hidden cameras, or check that all amenities are in order. But many people forget to examine one crucial spot — under the bed. That overlooked area can sometimes hide more than just dust — and that’s where this trick comes in.
According to Esther, a seasoned Dutch flight attendant with years of travel experience at KLM, she always throws a bottle of water under the bed before settling in. If the bottle rolls freely from one side to the other, the space is clear. But if it stops or fails to come out, it could mean there’s something — or someone — underneath.
This simple move spares you from having to bend down and risk an unpleasant surprise. Instead, you get a safe, hands-free way to check before unpacking your things.
If anything seems unusual, don’t hesitate — leave the room immediately and alert hotel security or the front desk.
Beyond safety, this trick also helps you assess the room’s cleanliness. Many cleaning staff overlook the space under the bed, where dust, trash, or even pests can accumulate. Spotting this early can help you request another room before it’s too late.
So, next time you check into a hotel, remember: toss a bottle of water under the bed first. It’s quick, simple, and could make your stay a lot safer and cleaner.
