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), length and beam (the width at the widest point).
