Seven Seas Grandeur: 21-Night Transatlantic

Messina cruise port sits at the northeastern tip of Sicily, directly across the narrow Strait of Messina from mainland Italy. Ships dock right at the city waterfront, making it one of the easiest Mediterranean ports to step off and explore.

Naples cruise port is one of the most popular stops on Mediterranean itineraries, and it's easy to see why. The city sits on the Bay of Naples with Mount Vesuvius looming behind it, and it serves as the gateway to Pompeii, the Amalfi Coast, Capri, and Sorrento.

Rome's cruise port is in Civitavecchia, a working port town about 80 kilometers northwest of the city. That distance is the single most important thing to understand about this stop.

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.
