Oceania Insignia: 25-Night World

Miami cruise port, officially called PortMiami, is the busiest cruise port in the world by passenger volume. Millions of people pass through here every year, and nearly every major cruise line uses it as a home port.

The Royal Naval Dockyard at Kings Wharf is Bermuda's primary cruise port, set within a restored 19th-century British naval base with shops, restaurants, and the National Museum. Bermuda's famous pink sand beaches and pastel-colored houses are accessible by ferry or bus.

Arrecife is the capital of Lanzarote, one of the Canary Islands in the eastern Atlantic Ocean about 125 km off the coast of West Africa. The island has about 155,000 residents and a landscape unlike anywhere else in Europe: volcanic craters, lava fields, black sand beaches, and an almost lunar terrain shaped by eruptions in the 1730s that buried a third of the island.

Santa Cruz de Tenerife is the capital of Tenerife, the largest of Spain's Canary Islands, located in the Atlantic Ocean about 300 km off the coast of Morocco. The cruise port sits in the heart of the city, directly adjacent to the commercial center and within walking distance of the main shopping street and waterfront.

Funchal is the capital of Madeira, a Portuguese island in the Atlantic Ocean about 600 miles southwest of Lisbon and 400 miles north of the Canary Islands. The island is volcanic, mountainous, and green, with a subtropical climate that keeps temperatures mild year-round.

Lisbon cruise port is one of the most atmospheric arrivals in Europe. Ships sail up the Tagus River past the 25 de Abril Bridge (a near-twin of San Francisco's Golden Gate) and the Christ the King statue, with the city rising up on seven hills to the north.

Porto is Portugal's second city, sitting on the steep banks of the Douro River near the Atlantic coast. Cruise ships dock at the port of Leixoes, an industrial harbor in the suburb of Matosinhos about 8 kilometers north of Porto's historic center.

Bordeaux is one of France's great cities, a UNESCO-listed urban center on the Garonne River in southwestern France known worldwide for its wine but increasingly recognized for its architecture, food scene, and cultural institutions. The Bordeaux cruise port is unusual: ocean-going cruise ships dock at the industrial port facility at Le Verdon-sur-Mer at the mouth of the Gironde estuary, about 100 km from Bordeaux city center, or occasionally at Bassens or Pauillac closer to the city.
