British tourists urged to check hotel mirrors to avoid a holiday from hell

British holidaymakers staying in hotels have been advised to check the mirrors for one ominous reason.

Many travellers prioritise a brief search of the hotel room when checking into their pad to ensure there are no unusual-looking stains or unexpected items lurking. But the hotel mirror is one part of the room we should all be adding to our list, and it's not for the reason you might think.

Over on social media, many holidaymakers have recounted tales of discovering two-way mirrors in their hotel, B&B, or holiday rental. For those unfortunate travellers, their holiday, which was meant to be a relaxing breakaway, turned into a holiday from hell.

In a bid to avoid the discomfort of knowing your privacy has been ripped away, John Cutts, founder of MeandMyGlass.co.uk and a mirror expert, has offered advice on how to determine if your hotel mirror is two-way.

He shared: "The thought of someone using a mirror to spy on guests is disturbing, to say the least. The good news is there are multiple ways you can check for a two-way mirror when staying in a hotel, motel or B&B."

John divulged his top five tips for determining whether a mirror is functioning both ways, reports the Express. Here's everything you need to know.

Try placing your fingernail onto the mirror, if there's no gap between your finger and its reflection, it could suggest a two-way mirror. With a standard mirror, there will be a gap between your fingernail and its reflection.

Sound can be a significant clue in determining if a mirror is two-way. Tap the glass around all four corners and in the middle. If it emits a hollow sound, there's a high chance there's something on the other side.

Stand facing the mirror and shine a torch on the glass to see if the light reflects back at you. If it doesn't bounce back, then the light will shine through on a two-way mirror, revealing what's behind the glass.

If the mirror is hanging, it's unlikely to be a two-way mirror. Two-way mirrors tend to be integrated into the wall rather than simply hanging on it.

Press your face against the mirror with your hands beside your head, blocking out any light. If the mirror is two-way, you might be able to see straight through.
