Regal Princess: 22-Night Mediterranean

London (Southampton) cruise port is the busiest cruise departure point in the United Kingdom and one of the largest in Northern Europe. The port sits in Southampton, a city on England's southern coast about 80 miles southwest of London.

Cadiz is the actual cruise port marketed as "Seville (Cadiz)" by cruise lines because Seville, Spain's fourth-largest city, is the primary day-trip draw from this port. Cadiz itself is one of Europe's oldest continuously inhabited cities, perched on a narrow peninsula jutting into the Atlantic on Spain's southwestern coast.

Barcelona cruise port is the busiest in the Mediterranean, handling millions of passengers a year across multiple terminals. The city behind it earns that traffic.

Florence (Livorno) cruise port is the main Tuscan stop on Mediterranean itineraries, but it's worth being clear about what you're actually docking at. The port is Livorno, a working industrial city on the Ligurian coast, about 85 kilometers west of Florence.

Ibiza is one of Spain's Balearic Islands in the western Mediterranean, about 150 km off the coast of Valencia. The cruise port is in Ibiza Town (Eivissa), on the southeast coast of the island.

Cartagena is a historic port city of about 215,000 people on Spain's southeastern Mediterranean coast, in the Murcia region. Founded by the Carthaginians in 227 BC (as Carthago Nova), the city has been contested by Carthaginians, Romans, Moors, and Spanish kingdoms, and its layered history shows in the archaeological sites scattered through the compact center.

London (Southampton) cruise port is the busiest cruise departure point in the United Kingdom and one of the largest in Northern Europe. The port sits in Southampton, a city on England's southern coast about 80 miles southwest of London.

Zeebrugge is a North Sea port about 15 km from Bruges, one of Europe's best-preserved medieval cities. Ships dock at Zeebrugge, but the destination is Bruges: a city of 120,000 people whose medieval center survived the centuries virtually intact because the city's commercial importance faded after the Zwin river silted up in the 15th century, and nobody had a reason to tear anything down.

Rotterdam is Europe's largest port city and a major cruise embarkation point in the Netherlands, located in the Rhine-Meuse-Scheldt river delta about 80 km south of Amsterdam. The cruise terminal (Rotterdam Cruise Terminal) is at the Wilhelminakade on the south bank of the Nieuwe Maas river, in the shadow of the Erasmus Bridge.

Oslo is Norway's capital, home to about 700,000 people in a city wrapped around the head of the Oslofjord with forested hills rising on every side. The city has undergone a dramatic transformation over the past two decades, with the harbor district rebuilt from industrial docks into a waterfront of museums, restaurants, and public spaces anchored by the angular white marble Opera House.
