Notable Rooms & Features


A 1,640-foot promenade on Deck 5 of Costa Cruises’ new Costa Diadema, will provide guests a new way to experience the Mediterranean. As the longest promenade of Costa’s fleet, it provides a 1,640-foot walk that will feel like a stroll on a gorgeous Italian shore. The spacious promenade measures 16 feet across and up to 26 feet wide where six cabanas and two Jacuzzis are located. The cabanas and hot tubs extend out from the side of the ship, creating the sensation of being suspended over the sea. In the cabanas guests can relax over drinks or enjoy a romantic sunset dinner, comfortably sheltered from the wind.

Bars and restaurants overlook the promenade, re-creating the atmosphere of a summertime Mediterranean beach. Guests can order a glass of top- quality Italian regional wine at Vinoteca Gran Duca di Toscana or a beer from Birreria, which offers a selection of bottled beer from renowned Italian and foreign brewers along with a range of beers on tap. Alternatively, guests can have an aperitif at Bar Bollicine, which features a wide selection of the most prestigious Italian brands of Prosecco and Spritz aperitifs.

After having a drink with a view of the sea and a stroll along Costa Diadema’s promenade, passengers will reach the elegant Teodora Bar at the stern.
