You can check if your hotel room safe is secure by testing the most common override codes – after Royal Caribbean passengers saw their valuables stolen in safe

BEFORE you lock your personal items away in the hotel room safe, you should first make sure it is secure.

An expert has explained that some hotels have very easy override codes - meaning anyone can easily gain access.

An eye-opening video shared on YouTube shows how easy it is for an intruder to break into certain safes once they have gained entry to your room.

In the the person in the film is seen setting their own personal code - just as any guest does when leaving valuables in their room.

After checking that the box is locked, the man then enters an incorrect code on purpose but is barred from opening the door.

However, the man then presses the "lock" button, followed by 999999, and the door opens.

According to the experts - the code 0000 is also often used by safe companies as a codebreaker.

The codebreakers are used as a safety mechanism in case the guest forgets their own code and the staff can open the door, but it also leaves the safe open to abuse from intruders.

As a result, all guests should check whether their own hotel safe has the same codebreaker before deciding whether to leave their own items alone on vacation.

Of course, there is only so much you can do to stay safe - one family found this out the hard way after all of their passports were stolen when their hotel safe was ripped out of the wall.

Cassandra Cahill, from the US, was travelling with her family around Rome when their hotel safe was stolen, which had their travel documents as well as credit cards and mobile phones.

Not only were they left stranded in Italy, but they also missed their European cruise as they could not board their Royal Caribbean cruise ship without identification.

They were forced to wait days for the embassy to open to get emergency passports.

Staying safe while on holiday is a big concern for most tourists and as a result, there are now hundreds of pricey gadgets that claim to deter would-be thieves and other criminals.

Another piece of hotel safety advice that seasoned travellers swear by more than any other for keeping them safe is the humble doorstop.

While most hotel rooms doors are fairly secure, even the strongest intruder would struggle to break through a door with a doorstop wedged from the other side.
