Specific rule on board world’s largest spicy cruise ship with 6,700 swingers will see you put in boat’s jail if you break it

The world's largest spicy cruise ship welcomes a staggering 6,700 swingers on board when setting jail. But it comes with a warning, with passengers potentially ending up in the vessel's jail for breaking one very serious rule.

Hosted on board Royal Caribbean's Symphony of the Seas, the Bliss Cruise holiday is loved by thousands of swingers every single time it sets sail from Miami, Florida.

One married couple recently took to TikTok to document their time on board the polygamous cruise, explaining what they got up to from the ordinary to the more unique.

But as with any holiday or excursion there are rules we all have to follow. And falling foul of them could land you in big trouble, with that trouble in this case being a cruise ship's jail.

Cruise ship rules

Bliss Cruise has many rules on board its Symphony of the Seas trip.

There are basic ones such as being at least 21 years old and showing respect to other passengers.

But given the nature of what goes down in the play rooms and private cabins, there is also an emphasis on consent.

"No means no. Anyone that doesn't understand this or is making unwanted advances could be subject to expulsion from the ship at the next port, without a refund," Bliss bluntly says on its website.

Being nude is also allowed but restricted in certain areas, such as the restaurants. In fact, you can only be without clothes on the outside decks, play rooms, and the sauna.

As for partaking in sexual activity, it is strictly only allowed in private cabins or in the designated play areas, of which there were three on the last cruise (including an open air one, fancy).

"Guests violating any rule pertaining to sexual activity in forbidden places may be removed from the ship by its security team at the next port of call. No refunds will be issued," the cruise holiday said.

Another key point stressed by Bliss was not to approach staff to get involved in these goings on, who will 'lose their jobs' if caught taking part.

What rule will land you in cruise ship jail?

It's all to do with what you bring on to the spicy cruise.

So if you think you can bring illegal drugs on board, you'll be in for a shock. The same goes for medicinal cannabis.

If you're caught with anything at the port when boarding, you'll be denied entry. And if you're caught with substances on board, it's jail-time for you.

Rule five on the Bliss Cruise website explicitly states: "Illicit and illegal drugs of any type, including medicinal marijuana, are not permitted on the ship.

"If found during the check-in process at the terminal, the cruise line will deny boarding.

"If found on the ship, the cruise line can and will most likely jail you until a port is reached where you will be handed over to the authorities, and possibly face criminal prosecution."

Bliss Cruise adds that 'no refunds will be issued if denied boarding or removed from the ship', so it's a lose-lose in every sense.
