Italy, Portugal & Morocco 11 Nights • Rome (Civitavecchia), Italy to Lisbon, Portugal • Mariner of the Seas

The Eternal City endures with endless adventures, so it’s definitely worth exploring before your cruise from Civitavecchia. Rome is just an hour from the port by train, so spending a few days here is easy and convenient. Start each morning with a frothy cappuccino and a warm, flaky cornetto in an al fresco café and watch the city wake. Then head to the Palazzo Massimo, home to one of the world's biggest collections of ancient art. Or visit the thermal Baths of Diocletian, where you can see two ancient, decorated tombs dating back to the early second century AD. And of course, no visit to Rome is complete without a trip to the famous Colosseum, which once hosted gladiator contests, battle reenactments and Roman dramas. If you’re a foodie, you’re in the right city. Roman cuisine is all about simple, fresh, unfussy flavors. Think thin and crispy pizza cooked in wood ovens, homemade pasta tossed in simple sauces, crispy fried vegetables and decadent breakfast pastries often stuffed with cream.

Sicily's capital city Palermo is a patchwork of influences from the Greeks, Romans, Arabs and Normans, all of whom have left their imprint here throughout the ages. Admire the diverse architecture of the Palazzo Reale, the historic seat of the kings of Sicily. Check out Piazza Vigliena, the 17th-century Baroque center square. Explore stunning mosaics at the Martorana. Or head to the top of Mount Pellegrino, where you can visit the enigmatic Shrine of St. Rosalia and take in vast views of the Golden Shell Valley.

All across Cagliari, you can find markings from past conquerers. Wander through the first-century ruins of Villa Tigellius to get a taste of the Romans. Step into the church of San Giacomo to find an architectural expression of Spanish affluence. Head to the historic old town to see medieval Torre dell'Elefante, a guard tower that dates back to 1307. Just a short walk away, you'll find the Bastione San Remy, the city's 19th-century fortifications.

After your arrive in Málaga, soak in the ancient history at La Alcazaba Moorish fotress and the ruins of the Roman Amphitheatre. Then, unwind on sunny La Malagueta beach or in the orchids and ferns at La Concepcion Botanical Garden. Check out the works of the city's most famous former resident at the Picasso Museum, and savor regional, fresh-caught pescado frito (fried fish) with a squeeze of fresh lemon.

Spend the day exploring Tangier, Morocco, before you set sail on your epic cruise. Begin at the iconic Kasbah, a hilltop fortress offering sweeping panoramas of the Mediterranean, or explore the Medina, a maze of bustling souks filled with spices, textiles, and handmade treasures. In this awe-inspiring city, continents meet and cultures blend in spectacular fashion. And it’s easily accessible, and the Tangier Ibn Battouta Airport is only a short drive away. A cruise to Tangier delivers an unforgettable blend of history, culture, and coastal beauty, leaving travelers with memories to last a lifetime.

As you depart the ship, you'll become aware of the hubbub: Casablanca is bustling, especially in the port. Head away from that area and into the city center, where you'll find tall Moorish buildings, like the Hassan II Mosque, or Art Deco landmarks, like the Sacré-Coeur Cathedral. From there, walk to where you can enjoy a snack or beverage in Place des Nations Unies — a bustling square filled with restaurants. Not sure what to indulge in? Seafood pastilla and snail soup are not to be missed. After you've filled up, it's time to try your hand at haggling in the souks. Watch the locals at Maarif Market strike bargains over fresh flowers, olives and spices before trying it yourself.

Portugal's Madeira island is a natural paradise. The lush mountains, brilliant flower gardens and jagged cliffs offer the perfect backdrop for an adventure-filled holiday. Break a sweat hiking one of the levandas, or cool off with a dip in the crystal-clear blue waters. Or indulge in some local cuisine, like grilled mussels or espetada, Madeira's answer to the grilled beef kebab.

Porto is a city that offers so much history and architecture to explore. Enter the Palacio da Bolsa to appreciate the decorative carvings and the traditional tile work. And if you've got your architecture fix taken care of then venture out to Foz do Douro, a trendy district that offers views of where the river enters the ocean and take it all in.

Fuel up for your Lisbon adventure with a delectable pasteis de nata, a sweet custard tart spiced with cinnamon and best savored warm. Then, climb the Seven Hills of Portugal and admire panoramic views of the sea and the city from above. Ride the yellow tram to explore every inch of colorful Lisbon. Wander along the seaside in the Belem district and marvel at the 16th-century architecture of the Jeronimos Monastery and Belem Tower.
