PortMiami
2451 departuresPortMiami calls itself the Cruise Capital of the World and the schedule backs it up: more ships turn around here than at any other port on earth. Royal Caribbean, Carnival, Norwegian, MSC and Virgin all keep year-round hardware at the terminals on Dodge Island, alongside the small luxury ships — Explora, Silversea, Regent, Seabourn, Oceania — that use Miami as their winter Caribbean base. The mix is unusually wide: three-night Bahamas hops on ageing Carnival tonnage share a berth with Icon of the Seas, the largest cruise ship ever built.
