Cruise secrets: Why can passengers never find this mysterious location on a cruise ship?

However, the omission of deck 13 on cruise ships is in fact to help passengers who might suffer from triskaidekaphobia.

Some cruisers may simply refuse to book rooms of the 13th floor.

Andy Harmer, SVP Membership Director, CLIA (Cruise Lines International Association) said: “As superstition goes, in some cultures the number 13 is considered ‘unlucky for some’.

“Like hotels around the world that don’t have a floor 13 or room 13, the cruise sector is very much the same with many of the cruise lines skipping out deck 13.

“With so many international holidaymakers choosing to take a cruise holiday, a number of cruise lines have chosen to do this, simply in line with the tradition.”
