Cruise secrets: The real reason passengers are most ‘seductive’ at sea revealed by crew

So it appears there may be science behind the author’s speculation, based on first hand experience.

Meanwhile, another ex employee has let slip the shocking amount of cabin crew relations on board.

Relationships between staff members is frowned upon, and between staff and passengers is completely forbidden, although that doesn’t seem to prevent some saucy action from happening on board.

Cathryn Chapman, who used to work on cruise ships in Australia, has opened up on the crazy antics on board.

Cathryn said: “Cheating was so rife that people were cheating on their partners at home, and then they would cheat on their partners on the ship while they were asleep or working…it was really bad.

“What I found quite shocking was people would have a girlfriend who lived in the cabin with them and then if the wife was coming on board they would move out the night before.

“They would stay away for two weeks while the wife was visiting, and then move back after she left like nothing had happened.'”
