Explorer of the Seas: 7-Night Italy & Croatia

Ravenna is a mid-sized city of about 160,000 people in Italy's Emilia-Romagna region, sitting on the Adriatic coast south of Venice. The city served as the capital of the Western Roman Empire, the Ostrogothic Kingdom, and the Byzantine Exarchate, leaving it with the finest collection of early Christian and Byzantine mosaics anywhere outside Istanbul.

Split cruise port is the main gateway to central Dalmatia and one of the most remarkable cities in Croatia. The city is built around and inside Diocletian's Palace, a 1,700-year-old Roman fortress that the emperor built as his retirement residence around 300 AD.

Dubrovnik cruise port is the southern gateway to Croatia's Adriatic coast and one of the most visually striking stops in the Mediterranean. Ships dock at Port Gruž, about 3 kilometers northwest of the Old Town, with the walled medieval city perched on a rocky peninsula jutting into the sea.

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.

Salerno is the eastern gateway to the Amalfi Coast, one of Italy's most celebrated stretches of coastline. Cruise ships dock at the Stazione Marittima in Salerno's port, a short walk from the city center and the starting point for trips along the legendary coastal road to Amalfi, Positano, and Ravello.
