It is also their 52nd consecutive cruise.

By the time they get off they will have will have done more than 26 months on the ship - much more than any of the crew.

And having spent so much time on cruise ships they of course have plenty of advice.

Here are their top tips.

Take a backup credit or debit card

"Replacing a lost or stolen card while overseas is not for the fainthearted," Marty said.

Take clear copies of your passports.

Consulates find it a lot easier if you can provide a copy ready to go when you disembark, they advised.

Wear your heaviest clothing

"Jessica and I have one piece of luggage, usually under 20kg," Marty said.

"We also each have one bag of hand luggage. Going on board, regardless of weather, I wear my heaviest clothing."

Leave toiletries at home

"Leave consumables like shampoo, conditioner, toothpaste and any creams and potions at home as Princess provides basic toiletries and anything you do need can be bought at the first port," Marty said.

Check electrical connections

"Check what electrical connection is used onboard and have the right adapter ready to charge your devices,' Marty said.

Many ships have American and European plug points, while newer ones may have USB connections too.

Get insurance

Make sure you're covered for cruising - and take a copy of the details, the couple said.

Bring prescriptions

As well as checking you have enough medication, you should also bring paperwork.

"As an extra precaution carry copies of scripts so that if you do run out or lose your medications it will be easier to prove what you need to overseas pharmacies or doctors," Marty said.

Pack essentials in hand luggage

It sounds simple but some people do forget.

When you get on a cruise your checked luggage is taken to your cabin and may take a few hours to arrive.

So you'll need to keep important items with you.

"Place all jewellery, passports, visas, medication money and credit/debit cards in your hand luggage for easy retrieval," Marty said.
