Dubrovnik, Croatia - Thick 16th-century stone walls encase the entire Old Town of Dubrovnik. But there are no boundaries on the endless adventures you’ll discover among its orange-roofed ramparts. With a made-for-TV appeal— Game of Thrones was actually filmed here— the city commands your attention with the perfectly preserved Rector’s Palace, elaborate Onofrio’s Fountain, and baroque St. Blaise’s Church, named after the city’s patron saint. You can browse museum collections showcasing Croatian artwork, period furniture and shipbuilding traditions. Stand in awe of the Franciscan Monastery library’s 30,000 volumes. Or to get your heart pumping, go cliff diving into the sea and kayak crystal blue waters, with the ‘Pearl of the Adriatic’ shimmering in the distance.

Kotor, Montenegro - Looking at a map of Europe, you might be forgiven for missing Kotor — a tiny port in the already-tiny country of Montenegro. But from the moment your Kotor cruise docks, you'll enter a larger-than-life world of mighty forts and towering sea cliffs, the air filled with the refreshing smell of the ocean. On a Mediterranean cruise, you can explore the attractions inside Kotor's fortified Old City, one of the Mediterranean's best-preserved medieval towns. Don't miss the Cathedral of St. Tryphon, an ornate church first consecrated in 1166. Then, scale St. John's Fortress — the hilltop fortifications, dating back to the 6th century, offer the best views of the city, the harbor and the surrounding mountains.

Corfu, Greece - Perched above the Adriatic Sea, Corfu, Greece is the second largest Ionian island, and its size is rivaled by its tremendous history and dynamic cultural identity. Cruise to Corfu and walk through the narrow streets of Old Town, a UNESCO World Heritage Site, and marvel at the Italianate architecture left from centuries of Venetian rule. A number of scenes from the James Bond film "For Your Eyes Only" were filmed in the capital city of Corfu, and you'll understand why when you see the epic coastal roads and immense fortresses buttressing the town. With its rich combination of old fishing villages and immaculate beaches, Corfu is the perfect place to get lost in time during your vacation.

Olympia (Katakolon), Greece - Experience ancient history and modern charm in Katakolon, a vibrant cruise port on the Greek coast. From here, you can catch a glimpse of Olympia, the birthplace of the original Olympic games and a shrine to the ancient Greek gods. Cruise to Greece and walk through the Olympia complex to get a historical tour of architectural styles, from the classical ruins to the red-tiled roofs of the traditional homes. Then, stroll through the Katakolon's lively center to discover unique local galleries and shops, and grab a seat at an oceanfront taverna with a glass of white wine and a dish of locally caught calamari.

Messina, Sicily - A beautiful sheltered harbor is your gateway to Taormina, a small town at heart despite its major tourist attraction: the sublime Teatro Greco, offering panoramic views of the coastline and snow-capped Mt. Etna.

Naples, Italy - Capital of Southern Italy, the largest city of Campania, Naples is the third most populated city in Italy (after Rome and Milan), with over a million inhabitants, and is the most important industrial center and trading port for the South. Naples itself can provide a day's fun and entertainment, if its somewhat rundown appearance doesn't dissuade you. Or, join a tour of incredible Pompeii, frozen in time since A.D. 79 when Mt. Vesuvius brought an end to that then-thriving city. Or, take a quick ferry across the bay to the flowery Isle of Capri. Or, (yes, there's more) visit fabulous Sorrento, vacation spot for the well to do.

La Spezia, Italy - La Spezia is a gateway to some of Italy's greatest treasures.

A quite pleasant small city itself, is located on a natural harbor and boasts a beautiful park parallel to its waterfront, substantial shopping, plenty of opportunities for good food, an archaeolgical museum in its historic hilltop fort and a nice contemporary art museum.

A short distance La Spezia and you are on the Cinque Terre ("The Five Cities") coast, a UNESCO World Heritage Site, and one of Italy's great natural jewels. These five small villages dotting the coast are free of car traffic and are reached only by a railway, hiking trails, or a pedestrian ferry. Small, winding paths connect many of the villages, and a light amount of hiking will afford you some spectacular views of cliffs, coastline, and stone terraces.

A little further afield is Pisa, one of the great renaissance cities whose ships dominated trade for decades. It is best known today, of course for it's famous "leaning Tower," from the top of which Galileo Galilei demonstrated that gravity's strength was independant of the weight of a falling object. It stands there still, if somewhat crookedly, after 650 years.

Sill further but worth the trip, is Florence where you can view the timeless treasures from the very height of renaissance achievements: the lofty Duomo, Giotto's gorgeous bell tower, Michelangelo's original David, the Uffizi Gallery, Ponte Vecchio over the Arno.
