Day 1 Naples, Italy

Naples, in the Campania region, is Italy's third largest city. Its claim to fame is the spectacular location along one of the world's most splendid bays, backed by the perfect cone of Mount Vesuvius. In addition to its beautiful setting, Naples' surprises with other outstanding attractions such as the Royal Palace, San Carlos Opera House, the impressive National Archaeological Museum and the Castel Nuovo, dating from the 13th-century. The city's central area is best explored on foot. Chaotic traffic conditions make driving around the city a very frustrating experience. Naples provides a convenient starting point for trips to such favored destinations as Pompeii, Herculaneum and Mount Vesuvius. The Isle of Capri can be reached via a 45-minute hydrofoil service. The region of Campania was home to Greeks settlers some 300 years before Rome was founded. Pompeii, too, was a Greek town before being conquered by the Romans during the 5th century BC. It was under the Romans that Pompeii flourished and grew prosperous. When Mount Vesuvius erupted in 79 AD, the population of 20,000 was wiped out, but dozens of buildings were preserved under layers of cinder more than 20 feet deep. The most important finds from Pompeii are displayed in Naples' National Archaeological Museum. A visit here will no doubt enhance a visit to ancient Pompeii.

Day 2 Livorno, Italy

Livorno is a gritty city with a long and interesting history. In the early Middle Ages it alternately belonged to Pisa and Genoa. In 1421 Florence, seeking access to the sea, bought it. Cosimo I (1519–74) started construction of the harbor in 1571, putting Livorno on the map. After Ferdinando I de' Medici (1549–1609) proclaimed Livorno a free city, it became a haven for people suffering from religious persecution; Roman Catholics from England and Jews and Moors from Spain and Portugal, among others, settled here. The Quattro Mori (Four Moors), also known as the Monument to Ferdinando I, commemorates this. (The statue of Ferdinando I dates from 1595, the bronze Moors by Pietro Tacca from the 1620s.)In the following centuries, and particularly in the 18th, Livorno boomed as a port. In the 19th century the town drew a host of famous Britons passing through on their grand tours. Its prominence continued up to World War II, when it was heavily bombed. Much of the town's architecture, therefore, postdates the war, and it's somewhat difficult to imagine what it might have looked like before. Livorno has recovered from the war, however, as it's become a huge point of departure for container ships, as well as the only spot in Tuscany for cruise ships to dock for the day.Most of Livorno's artistic treasures date from the 17th century and aren't all that interesting unless you dote on obscure baroque artists. Livorno's most famous native artist, Amedeo Modigliani (1884–1920), was of much more recent vintage. Sadly, there's no notable work by him in his hometown.There may not be much in the way of art, but it's still worth strolling around the city. The Mercato Nuovo, which has been around since 1894, sells all sorts of fruits, vegetables, grains, meat, and fish. Outdoor markets nearby are also chock-full of local color. The presence of Camp Darby, an American military base just outside town, accounts for the availability of many American products.If you have time, Livorno is worth a stop for lunch or dinner at the very least.

Day 3 Marseille, France

Since being designated a European Capital of Culture for 2013, with an estimated €660 million of funding in the bargain, Marseille has been in the throes of an extraordinary transformation, with no fewer than five major new arts centers, a beautifully refurbished port, revitalized neighborhoods, and a slew of new shops and restaurants. Once the underdog, this time-burnished city is now welcoming an influx of weekend tourists who have colonized entire neighborhoods and transformed them into elegant pieds-à-terre (or should we say, mer). The second-largest city in France, Marseille is one of Europe's most vibrant destinations. Feisty and fond of broad gestures, it is also as complicated and as cosmopolitan now as it was when a band of Phoenician Greeks first sailed into the harbor that is today's Vieux Port in 600 BC. Legend has it that on that same day a local chieftain's daughter, Gyptis, needed to choose a husband, and her wandering eyes settled on the Greeks' handsome commander Protis. Her dowry brought land near the mouth of the Rhône, where the Greeks founded Massalia, the most important Continental shipping port in antiquity. The port flourished for some 500 years as a typical Greek city, enjoying the full flush of classical culture, its gods, its democratic political system, its sports and theater, and its naval prowess. Caesar changed all that, besieging the city in 49 BC and seizing most of its colonies. In 1214 Marseille was seized again, this time by Charles d'Anjou, and was later annexed to France by Henri IV in 1481, but it was not until Louis XIV took the throne that the biggest transformations of the port began; he pulled down the city walls in 1666 and expanded the port to the Rive Neuve (New Riverbank). The city was devastated by plague in 1720, losing more than half its population. By the time of the Revolution, Marseille was on the rebound once again, with industries of soap manufacturing and oil processing flourishing, encouraging a wave of immigration from Provence and Italy. With the opening of the Suez Canal in 1869, Marseille became the greatest boomtown in 19th-century Europe. With a large influx of immigrants from areas as exotic as Tangiers, the city quickly acquired the multicultural population it maintains to this day.

Day 4 Barcelona, Spain

The infinite variety of street life, the nooks and crannies of the medieval Barri Gòtic, the ceramic tile and stained glass of Art Nouveau facades, the art and music, the throb of street life, the food (ah, the food!)—one way or another, Barcelona will find a way to get your full attention. The capital of Catalonia is a banquet for the senses, with its beguiling mix of ancient and modern architecture, tempting cafés and markets, and sun-drenched Mediterranean beaches. A stroll along La Rambla and through waterfront Barceloneta, as well as a tour of Gaudí's majestic Sagrada Famíliaand his other unique creations, are part of a visit to Spain's second-largest city. Modern art museums and chic shops call for attention, too. Barcelona's vibe stays lively well into the night, when you can linger over regional wine and cuisine at buzzing tapas bars.

Day 5 Valencia, Spain

Valencia, Spain's third-largest municipality, is a proud city with a thriving nightlife and restaurant scene, quality museums, and spectacular contemporary architecture, juxtaposed with a thoroughly charming historic quarter, making it a popular destination year in year out. During the Civil War, it was the last seat of the Republican Loyalist government (1935–36), holding out against Franco's National forces until the country fell to 40 years of dictatorship. Today it represents the essence of contemporary Spain—daring design and architecture along with experimental cuisine—but remains deeply conservative and proud of its traditions. Though it faces the Mediterranean, Valencia's history and geography have been defined most significantly by the River Turia and the fertile huerta that surrounds it.The city has been fiercely contested ever since it was founded by the Greeks. El Cid captured Valencia from the Moors in 1094 and won his strangest victory here in 1099: he died in the battle, but his corpse was strapped into his saddle and so frightened the besieging Moors that it caused their complete defeat. In 1102 his widow, Jimena, was forced to return the city to Moorish rule; Jaume I finally drove them out in 1238. Modern Valencia was best known for its frequent disastrous floods until the River Turia was diverted to the south in the late 1950s. Since then the city has been on a steady course of urban beautification. The lovely bridges that once spanned the Turia look equally graceful spanning a wandering municipal park, and the spectacularly futuristic Ciutat de les Arts i les Ciències (City of Arts and Sciences), most of it designed by Valencia-born architect Santiago Calatrava, has at last created an exciting architectural link between this river town and the Mediterranean. If you're in Valencia, an excursion to Albufera Nature Park is a worthwhile day trip.

Day 7 Casablanca, Morocco

The original settlement formed on the site of Casablanca by the Berbers became the kingdom of Anfa, and during the 15th century harboured pirates who raided the Portuguese coast. In retaliation for the attacks, the Portuguese destroyed Anfa and founded the town they called Casa Branca (white house). They remained here until an earthquake in 1755 and the town was subsequently rebuilt by Mohammed ben Abdallah, whose legacy of mosques and houses can still be seen in the old Medina. Casablanca acquired its present-day name when the Spanish obtained special port privileges in 1781. The French landed here in 1907, later establishing a protectorate and modelling the town on the port of Marseilles. Today Casablanca is Morocco's largest city, its most significant port and the centre of commerce and industry. The city is a vibrant fusion of European, African and Arabian influences and its French colonial architecture and art deco buildings seamlessly blend in with the busy, colourful markets. Please note that vendors in the souks can be very persistent and eager to make a sale.

Day 16 Bridgetown, Barbados

Located beside the island's only natural harbour, the capital of Barbados combines modern and colonial architecture with glorious palm tree-lined beaches and a number of historical attractions. Experience the relaxed culture of the city renowned for its British-style parliament buildings and vibrant beach life, and seek out the Anglican church and the 19th-century Barbados Garrison. The distance between the ship and your tour vehicle may vary. This distance is not included in the excursion grades.

Day 17 Saint George's, Grenada

Nutmeg, cinnamon, cloves, cocoa those heady aromas fill the air in Grenada (pronounced gruh-nay-da). Only 21 miles (33½ km) long and 12 miles (19½ km) wide, the Isle of Spice is a tropical gem of lush rain forests, white-sand beaches, secluded coves, exotic flowers, and enough locally grown spices to fill anyone's kitchen cabinet. St. George's is one of the most picturesque capital cities in the Caribbean, St. George's Harbour is one of the most picturesque harbors, and Grenada's Grand Anse Beach is one of the region's finest beaches. The island has friendly, hospitable people and enough good shopping, restaurants, historic sites, and natural wonders to make it a popular port of call. About one-third of Grenada's visitors arrive by cruise ship, and that number continues to grow each year. Grenada's capital is a bustling West Indian city, much of which remains unchanged from colonial days. Narrow streets lined with shops wind up, down, and across steep hills. Brick warehouses cling to the waterfront, and pastel-painted homes rise from the waterfront and disappear into steep green hills. The horseshoe-shaped St. George's Harbour, a submerged volcanic crater, is arguably the prettiest harbor in the Caribbean. Schooners, ferries, and tour boats tie up along the seawall or at the small dinghy dock. The Carenage (pronounced car-a-nahzh), which surrounds the harbor, is the capital's center. Warehouses, shops, and restaurants line the waterfront. The Christ of the Deep statue that sits on the pedestrian plaza at the center of The Carenage was presented to Grenada by Costa Cruise Line in remembrance of its ship, Bianca C, which burned and sank in the harbor in 1961 and is now a favorite dive site. An engineering feat for its time, the 340-foot-long Sendall Tunnel was built in 1895 and named for Walter Sendall, an early governor. The narrow tunnel, used by both pedestrians and vehicles, separates the harbor side of St. George's from the Esplanade on the bay side of town, where you can find the markets (produce, meat, and fish), the Cruise Ship Terminal, the Esplanade Mall, and the public bus station.

Day 19 Philipsburg, Sint Maarten (Dutch part)

The capital of Dutch St. Maarten stretches about a mile (1½ km) along an isthmus between Great Bay and the Salt Pond and has five parallel streets. Most of the village's dozens of shops and restaurants are on Front Street, narrow and cobblestone, closest to Great Bay. It's generally congested when cruise ships are in port, because of its many duty-free shops and several casinos. Little lanes called steegjes connect Front Street with Back Street, which has fewer shops and considerably less congestion. Along the beach is a ½-mile-long (1-km-long) boardwalk with restaurants and several Wi-Fi hot spots.Wathey Square (pronounced watty) is in the heart of the village. Directly across from the square are the town hall and the courthouse, in a striking white building with cupola. The structure was built in 1793 and has served as the commander's home, a fire station, a jail, and a post office. The streets surrounding the square are lined with hotels, duty-free shops, restaurants, and cafés. The Captain Hodge Pier, just off the square, is a good spot to view Great Bay and the beach that stretches alongside.

Day 20 San Juan (Puerto Rico), Puerto Rico

If you associate Puerto Rico's capital with the colonial streets of Old San Juan, then you know only part of the picture. San Juan is a major metropolis, radiating out from the bay on the Atlantic Ocean that was discovered by Juan Ponce de León. More than a third of the island's nearly 4 million citizens proudly call themselves sanjuaneros. The city may be rooted in the past, but it has its eye on the future. Locals go about their business surrounded by colonial architecture and towering modern structures.By 1508 the explorer Juan Ponce de León had established a colony in an area now known as Caparra, southeast of present-day San Juan. He later moved the settlement north to a more hospitable peninsular location. In 1521, after he became the first colonial governor, Ponce de León switched the name of the island—which was then called San Juan Bautista in honor of St. John the Baptist—with that of the settlement of Puerto Rico ("rich port").Defended by the imposing Castillo San Felipe del Morro (El Morro) and Castillo San Cristóbal, Puerto Rico's administrative and population center remained firmly in Spain's hands until 1898, when it came under U.S. control after the Spanish-American War. Centuries of Spanish rule left an indelible imprint on the city, particularly in the walled area now known as Old San Juan. The area is filled with cobblestone streets and brightly painted, colonial-era structures, and its fortifications have been designated a UNESCO World Heritage Site.Old San Juan is a monument to the past, but most of the rest of the city is planted firmly in the 21st century and draws migrants island-wide and from farther afield to jobs in its businesses and industries. The city captivates residents and visitors alike with its vibrant lifestyle as well as its balmy beaches, pulsing nightclubs, globe-spanning restaurants, and world-class museums. Once you set foot in this city, you may never want to leave.

Day 23 Miami, Florida, United States

Miami is one of the world's most popular holiday spots. It has so much to offer; from its countless beach areas, to culture and museums, from spa and shopping days out, to endless cuban restaurants and cafes. Miami is a multicultural city that has something to offer to everyone.
