There's something about mega-ships, those floating skyscrapers laid sideways. So here lies our list of the world's largest cruise vessels, ranked in order of gross tonnage, a measure of volume (and not weight).
You'll also find stats on passenger capacity (both double occupancy, the industry standard, and max occupancy, which accounts for all third and fourth beds onboard), length and beam, the width at the widest point of the vessel. We've listed the maximum beam, which is usually the beam of the upper pool deck as opposed to the actual hull at the waterline.
