The Costa Diadema will have you cruising Italian Style.

The Costa Diadema is perfect for families and couples alike, who thrill to films in the 4D cinema and go for virtual races in the amazing Grand Prix Simulator. Fun continues for the kids with the tasty Amarillo Ice Cream Parlour, and in the children’s’ pool, complete with a pirate ship and castle! Then there’s the exciting Star Lazer, an interactive laser zone with a twisting maze and shooting gallery.

Adults love the Costa Diadema’s four level-oasis, the Samsara Spa. This retreat features a sauna, Turkish bath, UVA-ray solarium, thalassotherapy pool, gym, and even cabins and suites in the wellness stateroom category. When it’s time to dine, cruisers enjoy seven restaurants, including Club Restaurant, Tavola Teppanyaki Restaurant, Samsara Restaurant, and the pizzeria. A variety of 11 bars and lounges include Dresden Green Pub, Gran Duca di Toscana Wine Bar.

You can choose from eight Jacuzzis and three swimming pools aboard the Costa Diadema, including one with a retractable roof! The Country Rock Club belts out everyone’s favorite honky tonk tunes, and the three-level theater hosts live performances.
