Among the special features not to be missed: an entire deck dedicated to children with castle and pirate galleon and the terrace on deck 5 for strolling and enjoying an aperitif at sunset: a real treat for holidaying in perfect Italian style. The cabins aboard our Flagship are elegant, well-appointed and spacious for up to five guests. At any time of the day or night you'll be spoilt for choice on what to do: sports, games, a large three-story theatre that welcomes international artists, and you too can take to the stage with Tu sì que Vales... and then the Aperol Spritz Bar for a cocktail before dancing the night away at the disco, a games room for returning to your childhood and a real German pub. We look forward to welcoming you on board.

About Savona
A part of the Italian Riviera near Genoa, Savona is a city rich in history and enterprise, largely centered around its port. A tour of the city may include a visit to "Columbus's House," a former residence of Christopher Columbus nestled in the Savona hills. Or one may visit Savona's most important monument, the Priamar, a recently-restored castle stronghold located near the port.
Savona Activities
Near the Rocca di San Giorgio, on the "Promontorio del Priamar", stands the fortress named Priamar, built after fall of Savona in Genoese hands (1528) by the Genoese in 1542, on the area of the old cathedral and old city and later used as a prison and military prison (italian patriot Giuseppe Mazzini was imprisoned here).
Near the Cathedral (built 1589 – 1604) is the Cappella Sistina, containing the tomb erected by the Della Rovere Pope Sixtus IV to honor his parents. The Cathedral has one of the most notworthy wooden choirs of XVI cent. European churches.
Facing the cathedral is the unfinished Palazzo Della Rovere, built by Cardinal Giulio della Rovere (Pope Julius II) from the plans of Giuliano da Sangallo as a university.
The old towers, survived after 1528 ruin (war with Genoa): the Campanassa (Commune tower where freedom of Savona was signed in 1191), towers Corsi and Riario, "Ghibelline Tower", and Torre della Quarda (also known as "a Torretta"), in Leone Pancaldo square.
The Sanctuary of Nostra Signora della Misericordia.
In neighbourhood of Savona remains a house documented as property of Domenico Colombo, father of Christopher Columbus, where they lived for many years (Christopher Columbus lived in Savona for much of his youth).
Located in the beautiful southern Catalonia region of Spain is Tarragona, where a rich cultural and artistic heritage is celebrated. There are eight active pottery centers in Tarragona, as well as other traditional Spanish arts and crafts such as lace-making, wrought iron works, glass blowing, and wood carving.
Stylish and friendly Valencia is together with Barcelona the most important city on the Spanish Mediterranean coast. While the original founding goes back to Roman times, it was the Moors who arrived in 709 AD and made Valencia prosper, thanks to a booming trade in paper, silk, leather, ceramics, glass and silver work. After Almanzor's death, the area was conquered by the legendary "El Cid" during the Christian re-conquest of Spain. Not much is left from the Roman period, but the architectural legacy of the Moors is abundant and can be seen in the remains of the old walls, the Almirante bath house and the tower, el Miguelete, which was the minaret of the old mosque.
Valencia Activities
Palacio del Marqués de Dos Aguas - This baroque palace is on the Calle del Poeta Querol. Extensively rebuilt during the 18th-century, it is fronted by an extravagant façade, hand carved in alabaster.
Torres de Serranos - This well-preserved 14th-century tower was part of the original walls that surrounded the old city.
Beaches - The main city beach is Playa de la Malvarrosa. It is not the most pristine beach in Spain and is lined with restaurants, bars and discos. About 5 miles south of the city is Playa El Salér, which is backed by attractive public gardens.
Founded nearly 26 centuries ago, Marseilles is the oldest city in France, a mosaic of old and new with a dozen villages and eight islands, each offering a world of enchanting discoveries. At nearby Avignon, visit the magmificient Palace of the Popes and the hilltop Basilica Notre Dame de la Garde. Explore ruins of 13th century Palais Longchamps and colorful "Old Harbour" where you can browse open-air markets.
Marseille Attractions
For the best view of the city, there's only one place to go: Notre Dame de la Garde. Entirely covered in gold leaf, it towers over Marseille at an impressive 500 feet tall (154 meters.) Throughout the years, it has served as a lookout post, a military zone and a place of worship.
Marseille Activities
Stroll around the Old Port, or Vieux Port as the locals say, which was once known as the gateway to the Mediterranean. Here you'll find the popular theatre, Théâtre National de la Criée, as well as many cafés and restaurants lining the streets.
See the amazing history of the city - 26 centuries worth - at Musée d'Histoire de Marseille.
Walk through Cours Julien, a pedestrian square with a beautiful water garden and fountain, as well as trendy shops, cafés and theatres.
Visit Le Prado south of the city where you'll find Parc Borély, a magnificent city park with numerous ponds, a botanical garden and a greenhouse.
