An independent ranking of the world's ultra-luxury cruise lines, the all-suite, all-inclusive ships where excursions, dining, drinks, and the flights are already in the fare.

Most cruise rankings are really popularity contests, ordered by how many berths a line can fill. This one is not. It ranks the small end of the market, the ultra-luxury cruise lines whose ships carry a few hundred guests instead of a few thousand, and where the fare is meant to cover the trip rather than open a tab.

We judge them on the things you cannot see in a photo of a balcony. How much space each guest actually gets, which the ship's tonnage and passenger count make impossible to fake. How good the food is once you leave the main dining room. How much of the holiday, the excursions, drinks, gratuities, and flights, is already inside the price. And whether the itineraries go somewhere worth the days at sea. Nobody pays for placement, and no free voyage buys a kinder verdict.

The lines at the top of these lists are not the biggest names in cruising, and that is the point. They are the ones that treat a small ship as the luxury, not a compromise, and that send you home having barely touched your wallet since you stepped aboard. If you have written off cruising, start here. This is the version that changes minds.
