Beautiful and innovative, Costa Cruises’ first Dream-class ship, the 132,500-ton, 3,724-guest Costa Diadema, is a spectacular ship. Deserving of her name meaning “tiara” in Italian, she is a sparkling jewel – the line’s largest, most spacious and modern, with a delightful international ambiance. She offers a variety of new dining and entertainment options. Delight in a multi-level spa, an open-air promenade with cabanas, dining venues and more. There is always something special and fun to do for all age groups.
