Pisa is a city in central Italy's Tuscany region best known for its iconic Leaning Tower (the bell tower of the city's cathedral). Although Pisa is known worldwide for its leaning tower, the city contains more than 20 other historic churches, several medieval palaces and various bridges across the River Arno. Much of the city's architecture was financed from its history as one of the Italian maritime republics. The city is also home of the University of Pisa, which has a history going back to the 12th century and also has the mythic Napoleonic Scuola Normale Superiore di Pisa and Sant'Anna School of Advanced Studies as the best sanctioned Superior Graduate Schools in Italy.

Monte Carlo, officially refers to an administrative area of the Principality of Monaco, specifically the ward of Monte Carlo/Spélugues, where the Monte Carlo Casino is located. Monaco has four traditional quarters - from west to east they are: Fontvieille (the newest), Monaco-Ville (the oldest), La Condamine, and Monte Carlo. Monte Carlo (literally "Mount Charles") is situated on a prominent escarpment at the base of the Maritime Alps along the French Riviera. Near the western end of the quarter is the world-famous Place du Casino, the gambling center which has made Monte Carlo "an international byword for the extravagant display and reckless dispersal of wealth". It is also the location of the Hôtel de Paris, the Café de Paris, and the Salle Garnier (the casino theatre which is the home of the Opéra de Monte-Carlo).

Civitavecchia is a town and comune of the Metropolitan City of Rome in the central Italian region of Lazio. A sea port on the Tyrrhenian Sea, the name ''Civitavecchia'' means "ancient town". The modern city was built over a pre-existing Etruscan settlement. The massive Forte Michelangelo was first commissioned from Donato Bramante by Pope Julius II, to defend the port of Rome. The upper part of the "maschio" tower, however, was designed by Michelangelo, whose name is generally applied to the fortress. North of the city at Ficoncella are the Terme Taurine baths frequented by Romans and still popular with the Civitavecchiesi. The modern name stems from the common fig plants among the various pools. And also next to the town is the location of the cruise ship docks. All major cruise lines start and end their cruises at this location, and others stop for shore excursion days that allow guests to see Rome and Vatican sights, which are ninety minutes away.
