This list includes some of the greatest, best-reviewed luxury cruise lines around, both in the U.S. and throughout the world. Which one is tops? That's for you to decide, with your votes. If luxury cruising is your thing, you'll want to seriously consider a vacation on board ships owned by one of these outstanding cruise lines. And, if your favorite luxury cruise line isn't listed, by all means, add it.

What makes a luxury cruise line the best? Often, the greatest luxury lines offer upscale amenities, fine dining and certainly plenty of staff to cater to your every whim. Sometimes the best cruise lines for luxury are smaller, with a better passenger-to-attendant ratio than some of the larger lines (which can carry thousands of passengers).

If your idea of a great cruise involves spa treatments, six-star service and cabins with balconies overlooking spectacular destinations, luxury cruising might be a dream come true. Many of the world's best luxury cruises are laid-back and all-inclusive, allowing passengers to pay one price and partake of everything the ship has to offer -- from food and drink to fancy shore excursions in some of the most magical cities in the world.
