A flight attendant has shared one unusual trick that people should do to be safe every time they check into a hotel room.
After having stayed in hundreds of hotels around the world, Esther, who flies for European airline KLM, said she always throws a bottle of water under the bed when she arrives.
Posting on her TikTok account, the experienced cabin crew member explained why it's so important, the Daily Express reports.

She said the game-changing hotel hack means you can easily spot if someone is hiding under the bed.
Esther said the bottle trick is a way to "check that no one is under the bed without looking".
She explained that travellers should simply "throw a bottle under it" and it "has to come out on the other side".
If it doesn't, it means that someone is hiding under the bed.
Another flight attendant posting on TikTok, Kat Kamali, also said it is crucial for people to check "if there's anyone in your room" as soon as they check in.
The American also said that travellers should never say their "room number out loud" and should make sure they check "behind the curtains and under the bed" as soon as they arrive.
Travellers on social media took to the comment section to share their thoughts with one saying that these were "super useful tips".
A second person said: "Super tips, especially the one under the bed!" and a third one added: "I'm dying about that bottle of water under the bed."
