Costa Diadema Review

Review of Costa Diadema

The 2014-built Costa Diadema cruise ship is a Dream-class liner, the flagship of Costa Cruises (replacing Costa Fascinosa) and the newest vessel in the fleet. "Diadema" means “tiara” in Italian.

The vessel (IMO number 9636888) is currently Italy-flagged (MMSI 247353700) and registered in Genoa.

History - Construction and Ownership

Costa Cruises is headquartered in Genoa and is a subsidiary of Carnival Corporation. Costa is Europe’s second-largest cruise line (after MSC Cruises) and operates year-round in the Mediterranean. Founded in 1854 as a cargo shipping company, Costa began passenger shipping services in 1947 with regular transatlantic crossings between Italy and South America. The company was acquired by Carnival Corporation in 2000.

Costa Diadema cruise ship

The 3800-passenger Costa Diadema was designed with numerous innovations in dining, entertainment, and onboard technology. Upon entering service, she became the largest Italian-flagged cruise ship afloat. While her design resembles Carnival’s Dream-class ships, Diadema is larger, features more onboard space, and introduces a new décor and design concept. Her refined elegance and inviting atmosphere ensure comfort and relaxation. Guests can enjoy a diverse culinary offering from around the world and indulge in wellness at the Samsara Spa.

In addition to her crew and staff, Costa passengers are assisted by Pepper robots, humanoid robots introduced fleetwide in 2016. These robots greet guests at embarkation and assist throughout the cruise with information on dining, entertainment, workshops, casino and shopping promotions, and shore excursions. Pepper robots are mobile, speak English, German, and Italian, and can interpret emotions through voice tone and facial expressions.

Decks and Cabins

Costa Diadema has 1886 staterooms in 15 categories, including 28 Suites, 905 Balcony cabins (100 of which are “Cove Balcony”), 240 Oceanviews, and 666 Inside cabins (17 for solo travelers). There are also 36 wheelchair-accessible cabins. A total of 161 Samsara Spa cabins are available, including 11 Suites, 90 Balcony, and 40 Interior staterooms.

The largest accommodations are the Grand Suites (275–345 ft² / 26–32 m²), with terraces ranging from 65–275 ft² / 6–26 m².

The ship has 14 passenger decks, with cabins located on 9 of them.

Shipboard Dining Options - Food and Drinks

Costa Diadema features seven restaurants, four of which require an additional charge (Samsara Restaurant, Club Restaurant, Teppanyaki, and La Piazza Pizza Pizzeria), along with 15 bars, including ‘Vinoteca Huit-Huit’, ‘Birreria La Fiamma’, ‘Bar Bollicine’, and ‘Gelateria Amarillo’.

Scudo Rosso Restaurant, the larger of the two main dining rooms (MDRs), spans the entire width of Deck 3 and is the only complimentary venue offering cooked breakfast with bacon and eggs. Sissi Restaurant, the second MDR, offers elegant décor with golden tones and mother-of-pearl accents, plus panoramic ocean views. It operates for dinner and occasionally lunch on sea days. Complimentary 24-hour room service is also available.

Costa Diadema Wiki

The vessel (Fincantieri Marghera yard/hull number 6203) has a volume of 133,019 GT, a DWT of 11,118 tons, and a maximum draught of 8.5 m. The powerplant is based on Wartsila marine diesel engines (models 12V46C and 8L46C) with a combined power output of 42 MW. The registered shipowner and management company is COSTA CROCIERE S.p.A., while the ISM Manager is CARNIVAL MARITIME GmbH.

Diadema is among Costa's largest liners. Following her inaugural cruise/maiden voyage (November 10, 2014, from Venice to Savona), she became the largest Italy-flagged vessel, replacing Costa Fascinosa as the fleet's flagship. Her sisterships from the DREAM-class (Carnival's "Fun Ships") include Carnival Breeze, Carnival Dream, and Carnival Magic.

At the time, Diadema represented Costa’s largest shipbuilding order, placed on August 3, 2011.

Her construction began with the keel-laying ceremony on December 10, 2012, at the Marghera Shipyard (Venice, Italy). The vessel was launched/floated out from drydock on November 16, 2013, officially delivered to Costa on October 25, 2014, and christened on November 7 in Venice. The inaugural cruise departed Venice on November 8. The 7-day Western Mediterranean itinerary included calls to ports in Italy (Naples, La Spezia, Savona), Spain (Barcelona, Palma de Mallorca), and France (Marseille).

Diadema was the first cruise ship to debut a laser maze show, allowing all guests to participate in the race. In 2016, Costa trialed its 4GOODFOOD program on Diadema, aimed at reducing food waste. The initiative achieved approximately a 50% reduction in food waste and up to 20% lower food consumption at the onboard self-service buffet restaurants.

In 2017, Diadema became the first ship in the fleet to introduce onboard-made, certified mozzarella produced from buffalo milk. The product, branded "Latteria del Curatino," was developed through a partnership with two Campania-based dairy companies—"Comat" (a dairy equipment manufacturer) and "Podere dei Leoni" (a leading producer of certified buffalo mozzarella). With this innovation, Costa became the world's first cruise company to serve freshly made mozzarella at sea.

Costa Diadema’s most recent drydock refurbishment was conducted from November 5-19, 2023, at Chantier Naval de Marseille (France). The project included general maintenance, classification inspections, technical overhauls, and extensive renovations and upgrades to all public areas, venues, and passenger staterooms, including new carpeting and soft furnishings.
