Costa Diadema costa-diadema

Discover all the best of Italy on board the new “Regina del Mediterraneo”: from its cuisine to its hospitality, from its design to its entertainment, Costa Diadema offers a wealth of new ways to enjoy cruising. The Terrace on deck 5 - over 500 metres long - is lined with bars and restaurants that will make you feel like it's a summer's day on the Italian Riviera every day.


You'll feel at home right away on a Costa holiday. There are cabins to suit everyone in terms of space, practicality and location and you won't have to give up any of the comforts you need to relax. All cabins are all furnished in a modern style, and a full range of facilities together with excellent service means that everyone can just relax and enjoy the cruise. Every Costa cabin features:

  • adjustable air conditioning with individual temperature controls;
  • interactive flat-screen satellite TV;
  • hair dryer;
  • safe;
  • steward, always on duty;
  • minibar and 24-hour room service (charges apply);
  • Wi-Fi (charges apply);
  • soap and shower gel;
  • bed linen (sheets and towels) changed regularly.

And you'll enjoy all these facilities even more thanks to prompt cabin service that anticipates your every need and ensures that your cabin is always clean and tidy. Every morning your cabin and bathroom will be cleaned and tidied. Every evening your cabin will be cleaned to remove litter, change your pool towel and any discarded towels and to make up your bed for the night, close your curtains and turn on your lights to welcome you when you return. 


Food & Drink

On your cruise, every breakfast, every lunch, every dinner and every snack will have its own special ingredient: the flavour of Italy that is all around you on a Costa holiday. All the restaurants serve specialities made with top-quality ingredients and prepared with the love of food for which Italians are famous.

Each morning there is a buffet breakfast with traditional Italian items, including a wide range of breads, croissants, sweets and cakes - all homemade - as well as cold cuts, cheese, fruit, yoghurt and cereals. Every day, for both lunch and dinner, a region of Italy will be the special guest at your table, with menus inspired by traditional local cuisine: you can try the famous fillet of beef Rossini on the day dedicated to the Marche region, cappelletti pasta with braised beef from Emilia Romagna, or exquisite Sardinian fregola pasta with fresh vegetables. And for anyone who wants to enjoy the most sophisticated Italian delicacies, the menu offers a selection for a small extra charge: delicious Grana Padano cheese and Parma ham, the genuine Milanese 300 g veal cutlet and the freshest shellfish.
