Cruise trips are the best way to see many countries in one go, with itineraries featuring a range of holiday destinations to see.
Caribbean islands are easily explored by water, being some of the most popular cruise holidays.
Some destinations however have different customs and laws that Britons may not be aware of.
There is one law that if broken could see huge fines or even jail time.
Displaying public affection is not allowed by law in a number of countries, particular ones that are strongly Islamic or Hindu.
Cities in the United Arab Emirates (UAE) such as Dubai and Abu Dhabi are especially strict, seeing kissing in public as an indecent offence.
Egypt and Indonesia can frown upon public displays, as well as Jordan and Morocco.
It could result in being fined or deported, while some tourists have even been arrested.
People who are not married also face the same punishment for the offence.
Passengers who choose to disembark at these destinations are advised to keep their PDA to the ship to avoid angry looks.
Many Middle East cruises dock at Dubai, with the holiday location one of the most popular for Britons looking for sun and luxury.
The Foreign Office warns travellers in Dubai: “Public displays of affection are frowned upon, and there have been several arrests for kissing in public.”
A similar warning is in place for Morocco: “Avoid public displays of affection, particularly outside the main tourist areas and near religious places.”
Homosexuality is also severely frowned upon or against the law in the countries, with British couples not exempt from the law.
It’s not the only unusual rule cruise passengers have to follow when making land.
Wearing camouflage clothing is against the law in a number of Caribbean islands.
This is because it is seen to represent the army which is illegal for normal citizens to do.
Travellers must abide by the rules so any camouflage clothing such as shorts or hats are to be left on the ship.
Children are not exempt from the rule and should also follow the local law.
