In this enchanting city the past and present intersect in perfect harmony. Casually intermingled among ancient ruins and majestic cathedrals are the trappings of a modern metropolis: Skyscrapers,cafes, boutiques selling designer footwear. But of course what you seek first in the heart of Rome is its breathtaking history. A good place to begin is the Vatican, with its Sistine Chapel and St. Peter's Basilica. Works by Bernini, Michelangelo, Caravaggio, and Raphael are just a few of those on display, any one of which is worth hours of contemplation. Then the ancient ruins—Colosseum, Forum, Circus Maximus. And of course the Trevi Fountain for the obligatory coins promising your return to the Eternal City.

Less than two hours from Rome, the port city of Naples was founded by the Greeks, is a UNESCO World Heritage Site and is unlike any other city in Italy. It is a busy, bustling place where mini-operettas take place on street corners, Vespas scoot across the pedestrian piazzas, the small narrow streets are hanging thick with laundry and graffiti is everywhere. But Naples is full of archaeological treasures that are among the most impressive in the world, including breathtaking frescoes and sculptures. Its beautiful palaces, castles and churches make Rome look provincial. And the food in Naples is among the best you'll find in Italy, serving decadent pizza, pasta, coffee, and seafood dishes you'll never forget.

The cobblestone streets of Messina, Sicily, are the perfect launching point for an optional visit to nearby Taormina. Stroll along flower-filled streets in search of a delightful lunch or an artist's palette of colorful gelati. The ancient Greek Theater is an ideal place to sit back and admire shimmering waters below and Mount Etna, languidly smoking in the distance.

While larger ships must pass by, we anchor right beyond the famous walled city so you can admire its beauty with every glance. Tender ashore and step right into Old Town, a UNESCO site where no cars are allowed, just eons of history. Capture the exhilarating views on your camera — and in your memory. End your day at the Buza Café (if you can find it) watching bold divers leap off the cliffs into the crystalline sea.

Something here will capture your heart. A Roman amphitheater, 9th century churches, and museums packed with Byzantine-era artworks crowd the peninsula that tidily contains the Old Town. It's a tempting way to spend the day for sure. While away the day listening to Zadar's giant Sea Organ, a haunting musical improv performed by the surging Adriatic or share a bench with a sun-drunk cat as you bite into a truffle.

No other sea approach in the Adriatic raises goose bumps like Venice, a small ship exclusive where the entire city and its lagoon are a UNESCO World Heritage Site. On your luxurious home-away-from home, you arrive already equipped with a sense of what it's like to live in the city that's neither land nor water. Add your own sigh to the Bridge of Sighs, sip a spritz al bitter as you plot your agenda, and let the water taxis do your navigating unless you don't mind getting lost. Not such a bad prospect, with serendipitous discoveries around every corner.
