Carnival Cruise Line just explained why it’s so important to close your curtains in your cabin

Carnival Cruise Line has issued a 'cabin flasher' warning to all its guests after a rather unfortunate incident on a recent holiday.

The incident happened on a Carnival cruise ship that had been docked in port, with one particular passenger left absolutely distraught at what she had accidentally been showing the entire world.

Carnival Cruise Line's brand ambassador and senior cruise director, John Heald, was forced to post a lengthy statement on the incident so that other passengers don't fall foul of the same faux pas.

The issue came as a result of going to sleep in one place and waking up in a very different part of the world - with a very different setting outside of their cabin.

'Cabin flashers'

"Are you a cruiser who likes exposing yourself? Come on, we are all mates here," Heald playfully wrote on his Facebook page. "Do you cover up or do you say, 'No, sod it, what’s the point having this and not showing everyone else how amazing it is?'.

"If you do then I am sorry but you are a flasher. A cabin flasher."

Adding a bit more context to the situation, Heald said he was 'talking about people leaving the curtains open so that when you dock in port and there is a ship docked right next to you they can see into your cabin'.

From there they can 'have a good view of everything in the cabin and possibly you wearing a Carnival bathrobe that is not one size fits all'.

Guests 'enjoying the show'

Heald explained that one recent incident on the Carnival Liberty was what prompted his gentle reminder to guests.

He said that one woman in particular 'had not drawn the balcony cabin curtains before going to bed and both her and her partner, woke up, stood up and started to potter about the cabin 'au naturel' as they say in Cleveland, Ohio, before realising that guests on the Carnival Legend were enjoying the show'.

An absolutely mortifying situation to come to terms with.

"It is perhaps a warning to close the curtains if you have a balcony or ocean view cabin," Heald advised.

It is just the latest bit of advice courtesy of Heald, who recently told passengers about important travel documentation changes they needed to be aware of if they were set to visit the UK or Europe.

He has also issued a warning about the important safety reason behind not drying your clothes on your cabin balcony.
