Costa Diadema
Costa Diadema, launched in 2014, is built for relaxation and fun with lots of on-board activities, scintillating bars, gourmet restaurants and the spa area.
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.
