The ship will become the flagship of the Costa fleet with a total passenger capacity of 4,947, 1,253 crew embers and 1,854 cabins.
The project involves approximately 1,000 shipyard workers and another 2,500 from linked industries.
The employment benefits also about 400 outside companies, the majority of which are Italian.
Costa Diadema will be bigger, more spacious and more modern in terms of the services offered.
The layout of public areas have been redesigned in a way to incorporate large environments over multiple levels facing the sea, that recreate the atmosphere of a lively beach side resort, connected by pathways that allow guests to move freely from one area to the other.
Costa Diadema is designed to offer a variety of experiences and activities for its guests, from new and enticing gastronomic and tasting opportunities, in places like the Vinoteca and the Proseccheria, the Bavarian-style Birreria, the Japanese Teppanyaki, the Piazza Pizza pizzeria and the Gelateria, to fun-filled innovations such as the Country Rock Club or the Lazer Maze, a multifunctional room with interactive games.
Shopaholics will enjoy the Portobello Market Square in a spacious area filled with shops.
The new ship also contains a three-level Samsara Spa with an exclusive outdoor area where guests can enjoy their holiday in an atmosphere of total wellness and relaxation.
