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).

Cartagena is a Spanish city and a majornaval station located in the Region of Murcia, by the Mediterranean coast, south-eastern Spain. The metropolitan area of Cartagena, known as Campo de Cartagena, has a population of 409,586 inhabitants. Cartagena has been inhabited for over two millennia, being founded around 227 BC by the Carthaginian Hasdrubal the Fair as Qart Hadasht, the same name as the original city of Carthage. Much of the historical weight of Cartagena in the past goes to its coveted defensive port, one of the most important in the western Mediterranean. As far back as the 16th century it was one of the most important naval ports in Spain, together with Ferrol in the North. It is still an important naval seaport, the main military haven of Spain, and is home to a large naval shipyard. The confluence of civilizations as well as its strategic harbour, together with the rise of the local mining industry is manifested by a unique artistic heritage, with a number of landmarks such as the Roman Theatre, the second largest of the Iberian Peninsulaafter the one in Mérida, an abundance of Phoenician, Roman, Byzantine and Moorish remains, and a plethora of Art Nouveaubuildings, a result of the bourgeoisie from the early 20th century. Cartagena is now established as a major cruise ship destination in the Mediterranean and an emerging cultural focus. It is the first of a number of cities that eventually have been named Cartagena, most notably Cartagena de Indias (Cartagena of the Indies) in Colombia.

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.
