Day 1 Civitavecchia, Italy

Italy's vibrant capital lives in the present, but no other city on earth evokes its past so powerfully. For over 2,500 years, emperors, popes, artists, and common citizens have left their mark here. Archaeological remains from ancient Rome, art-stuffed churches, and the treasures of Vatican City vie for your attention, but Rome is also a wonderful place to practice the Italian-perfected il dolce far niente, the sweet art of idleness. Your most memorable experiences may include sitting at a caffè in the Campo de' Fiori or strolling in a beguiling piazza.

Day 2 Palermo, Italy

Once the intellectual capital of southern Europe, Palermo has always been at the crossroads of civilization. Favorably situated on a crescent-shaped bay at the foot of Monte Pellegrino, it has attracted almost every culture touching the Mediterranean world. To Palermo's credit, it has absorbed these diverse cultures into a unique personality that is at once Arab and Christian, Byzantine and Roman, Norman and Italian. The city's heritage encompasses all of Sicily's varied ages, but its distinctive aspect is its Arab-Norman identity, an improbable marriage that, mixed in with Byzantine and Jewish elements, created some resplendent works of art. No less noteworthy than the architecture is Palermo's chaotic vitality, on display at some of Italy's most vibrant outdoor markets, public squares, street bazaars, and food vendors, and above all in its grand climax of Italy's most spectacular passeggiata (the leisurely social stroll along the principal thoroughfare).

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 Cádiz, Spain

Believed to be the oldest town on the Iberian Peninsula, the Andalusian port of Cádiz enjoys a stunning location at the edge of a six-mile promontory. The town itself, with 3,000 years of history, is characterised by pretty white houses with balconies often adorned with colourful flowers. As you wander around be sure to take a stroll through the sizeable Plaza de Espãna, with its large monument dedicated to the first Spanish constitution, which was signed here in 1812. Cádiz has two pleasant seafront promenades which boast fine views of the Atlantic Ocean, and has a lovely park, the Parque Genoves, located close to the sea with an open-air theatre and attractive palm garden. Also notable is the neo-Classical cathedral, capped by a golden dome.

Day 9 Santa Cruz de Tenerife, Spain

The largest of the Canary Islands, Tenerife is a beautiful and scenic island which enjoys year-round sunshine and is dominated by Mount Teide. The mountain range runs through the centre of the island, with fertile valleys on the northern side. In the central part of the range is the gigantic natural crater of the Cañadas del Teide, about 14 miles in diameter. Santa Cruz, the island's pretty capital, was originally a small fishing village but has now grown into a modern city, and also contains 16th-century civic buildings and ornate private mansions. Near the pier is the Santa Cruz Palmetum, a Botanical Garden covering an area of 29 acres, specialising in palms.

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 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 22 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.
