Vacations are supposedly a time of adventure, relaxation, and happy memories. But sometimes, things don’t go as planned, and the places we stay become the stuff of nightmares. From creepy encounters to sh0cking surprises, these travelers had experiences they’ll never forget—for all the wrong reasons.

I discovered a hidden camera in our Airbnb bedroom. It was midnight. My husband quickly covered it with a towel, and we went to sleep.At 2 a.m., the door burst open. The Airbnb owner stormed in, furious, screaming, “You idiots, this is a camera to see the outside! Why have you covered it?”

It turned out the camera was aimed at the street, not the bedroom. The owner, paranoid from a string of thefts in the neighborhood—including the theft of his car—had installed it to watch for trouble. He admitted to monitoring the footage obsessively.

We left first thing in the morning, feeling shaken and uncomfortable. Despite his explanation, breaking into our room in the middle of the night crossed every boundary. We left an honest review, warning future guests about the intrusion.
