A revelation about upside-down pineapples on cruise ship cabin doors has taken many passengers by surprise.
Cruising has evolved from being primarily for older travelers to offering something for everyone. It’s a lifestyle choice for some, such as a couple who decided to “sell everything” to live on a ship indefinitely, with others following similar paths to save money.
While seasoned cruise-goers might think they’ve seen it all, there’s a subtle message on cabin doors that remains undiscovered by many.
Curious TikTok user Dominique @blogionistatravels noticed the appearance of upside-down pineapples on some cabin doors and wondered about their significance.
“When you’re on your first cruise and you see that everyone has these little cute pineapples on their door,” she noted in a viral video.

Many TikTok users quickly informed her that these ‘cute’ pineapples actually signal something quite adult in nature.
“Those people are swinging. I learned that at a young age from my first cruise,” one commenter shared. “Omg I found out what they mean last cruise we went on. It means, drop-ins are most welcome…and bring friends.”
This revelation left many viewers astonished, with some advising the TikToker to ‘keep walking’.
The upside-down pineapple symbol is commonly used on swinger cruises and in everyday contexts as a discreet sign that someone is part of that lifestyle.
TikTok couple Belle and Jase have also encountered upside-down pineapples while on a cruise.

There are other indicators for those seeking adult fun besides the pineapple decor.
In one of Belle’s videos, she mentions that during the ‘spicy cruise’ she attended, participants were required to wear necklaces displaying their names.
The pineapple holds particular importance, with Belle even speculating about its consumption within the community.
“I bet swinger cruises go through way more pineapple than normal ones do, don’t you think?” she humorously suggested.
In any case, if you spot an upside-down pineapple in your vicinity, it may indicate the presence of swingers. However, respect their privacy; the symbol is meant to be discreet for a reason.
