The towel 'golden rule' all passengers must follow on a nude cruise

A nude cruise guest has revealed the 'golden rule' all passengers must follow if they're embarking on a trip.

Nude cruises are becoming increasingly popular, with several companies now offering the packages.

One person, who recently returned from a nude cruise, shared a Reddit thread where they invited people to ask them questions about some of the rules, and what people get up to on the nude holidays.

In the post, they responded to some of the most popular questions, explaining that members of staff on the cruises were always dressed, meanwhile it was on the whole an 'older crowd' as opposed to younger guests.

It's also important to point out that nude cruises are not to be confused with 'spicy cruises', aimed at those who want to explore non-monogamy on their holidays.

The passenger also revealed there's one 'golden rule' that all guests must follow, and the reason why makes a lot of sense.

One person asked: "Do you carry a towel everywhere you go? It seems rather gross to have multiple naked sweaty bodies sitting or laying on everything that everyone uses."

The Redditor explained: "No bare butts on any surface in any public space. Ever. That's not a difficult concept. Nudists are as interested in hygiene as much as if not more than the next guy."

Over on one cruise line's website, Bare Necessities, they explain: "Please sit on a towel at all times while nude, in a G-string, thong, or any time you are bare-bottomed. A fresh beach towel will be provided in your stateroom each day for that purpose. Stacks of smaller towels will be placed throughout the ship outside of common areas in case you arrive without one."

There are a number of other rules that guests are expected to follow, including designated areas where clothes must be worn.

Bare Necessities explain: "When the ship is at sea or anchored in a port, passengers can be nude unless announcements have been made to the contrary.

"When the ship is docked alongside in port, all passengers must be dressed throughout the vessel, including balconies, until the ship leaves port and an announcement is made that nudity is again permissible."

Meanwhile, there are different rules while dining, too.

"The self-serve buffet is a clothes-free area. Clothing is required for all meals taken in the dining rooms. Casual attire is fine in all of these venues. Bathrobes are not permitted in the dining room," they explain.

"When in doubt as to what is appropriate attire, simply confirm that breasts, bottoms and genitalia are fully covered by clothing that is not considered to be fetish-wear or lingerie. Lingerie, fetish-wear, and excessive genital jewelry are not appropriate at any time."
