Not only will the ultimate cruise take you on a 12-month long holiday but this brilliant cruise idea from Planet Cruise is actually cheaper than living on land for a year - yes, cheaper!
The 2017 cruise, which costs £24,000 for a 52-week voyage, save you £5,712, based on the average cost of living in London for a year at £29,712. And this is with wall-to-wall luxury on the open seas, fine dining, spa treatments and stopovers across the globe thrown in.
On travel agent Planet Cruise's holiday, you can expect food, entertainment and accommodation for a whole year. You don't have to compromise on surroundings either as the 2017 cruise takes in stunning stopovers, such as the Canaries at Christmas and Spain in the summer. It works on a cruise hopping system, so, for instance, if you start the cruise in March, you could spend the first half of the month on a Royal Caribbean cruise around Dubai and Oman, enjoy the second part of the month cruising around Brazil with Costa Cruises, then begin April in the Canaries with Cruise & Maritime before joining another ship to somewhere else.
With this in mind, we thought we'd look at more of the world's longest cruises, which are perfect for those who don't fancy swapping ships or prefer to spend less time at sea...
