Costa Diadema, launched in 2014, is the latest addition to our fleet. It is built for relaxation and fun with lots of on board activities, lively bars, gourmet restaurants and the spa area.

Among the special features not to be missed: an entire deck dedicated to children, complete with a castle and pirate galleon, plus the terrace on deck 5 for strolling and enjoying an cocktail at sunset: a real treat for vacationing 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 theater where international artists, and you too can be in the show 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.

Towards the stern on deck 5 you'll find the Teodora Bar, with tables and armchairs lining a large dancefloor, for nights of Latin American music. Here you can relax between one song and the next with a cocktail in hand in the perfect setting. But there's more, the Teodora lounge opens out onto a square overlooking the sea at the stern of deck 5, from where you can watch the ship's wake to a rhythmic beat. 

Pietra di Luna Disco
The night comes alive at the disco on decks 11 and 12, where the flashing lights and bright colours are joined by the moon's rays reflecting off the sea. Get your dancing shoes on, because here you can boogie the night away to all the latest hits from our DJs. What will your holiday song be?

Orlov Grand Bar
The Orlov Grand Bar has a wonderful '50s feel to it. Warm colours alternate with mother-of-pearl and light woods, bringing out the touch of pink in the decorated ceiling, creating the perfect mood for drinks with friends. What makes it even more special is the stage for live shows. Just sit back and relax, and enjoy performances by talented international artists. On Costa Diadema every moment is an event.

Country Rock Club
Does the twang of a country guitar bring out the cowboy in you? You've come to the right place: the Country Rock Club is the place to be for the real spirit of America and for the best live country rock music. Just like in the real West Coast saloons, you can order at the bar, take a seat on a high stool and tap your feet in time to the music. Get ready for Costa Diadema's country rock side.

Emerald Theatre
Just like a jewel, the surfaces of the Emerald theatre reflect the light and make the furnishings sparkle - furnishings decorated with details of precious stones. Spread out over three decks, Costa Diadema's glittering theatre is waiting to put on its spectacular shows just for you, with international dancers, singers and artists.
