Oceania Vista: 20-Night Mediterranean

Doha is the capital of Qatar, a small, wealthy Persian Gulf state on a peninsula jutting into the Arabian Gulf. The city has about 2 million people in its metropolitan area and has transformed from a quiet pearling and fishing port into one of the most architecturally ambitious cities in the Middle East, fueled by natural gas wealth.

Dubai is a city built on ambition and air conditioning, rising from the Arabian desert into a skyline of record-breaking towers, artificial islands, and mega-malls. The Dubai cruise port at Mina Rashid sits in the older part of the city near the historic Creek district, about 15 minutes from the modern skyscraper core along Sheikh Zayed Road.

Rhodes is the largest of Greece's Dodecanese islands, sitting in the far southeastern Aegean Sea just 18 kilometers from the Turkish coast. The Rhodes cruise port is in the city of Rhodes on the island's northern tip, where ships dock right next to one of the best-preserved medieval old towns in Europe.

Kusadasi cruise port is Turkey's busiest and the primary gateway to Ephesus, one of the most significant ancient Greek and Roman cities in the world. The port sits on Turkey's central Aegean coast, about 95 kilometers south of Izmir, with ships docking at the Ege Ports cruise terminal right in the middle of town.
