A separate link provides an extensive information on Costa Diadema staterooms (cabins and suites), including photos, cabin plans and amenities by room type and category.

Costa Diadema (2014-built, last refurbished in November 2023) is a Dream-class Costa cruise ship. She has four sisterships in the Carnival Cruise Line fleet: Carnival Dream, Carnival Magic, and Carnival Breeze. These are among the largest cruise vessels ever built in Italy by Fincantieri. The name "Diadema" means "tiara" in Italian.

The Costa Diadema cruise ship deck plan includes a total of 1886 staterooms for 3772 passengers (maximum capacity 4526), served by 1250 crew members. The vessel has 14 passenger decks (out of 17 total), 7 restaurants, 15 lounges and bars, 3 swimming pools (one with a retractable glass roof), 8 jacuzzies, and 18 elevators (including 4 panoramic lifts). There are no self-service laundromats onboard.

A total of 190 original artworks and 7874 prints are displayed throughout the ship in various public areas.

In addition to the ship’s crew and staff, Costa passengers are also assisted by Pepper robots—a state-of-the-art humanoid technology implemented fleetwide in 2016. These robots greet and guide guests during embarkation and provide assistance throughout the voyage, offering information and tips on onboard dining, entertainment, enrichment programs (workshops and scheduled events), casino and shopping promotions, and shore excursions. Pepper robots are mobile and communicate in three languages (English, German, and Italian). They are also capable of interpreting human emotions by analyzing voice tone and facial expressions.
