Overview

The 4,947-passenger Costa Diadema first set sail in 2014 as one of the largest ships in the Costa fleet. Foodies will love that in 2016 the ship became the first in the world to produce fresh mozzarella on board. While there are seven restaurants for passengers to pick from, including four specialty venues that require an extra fee, some travelers said slow service and extra charges at dinner tarnished their dining experiences.

Cruisers were more pleased with their staterooms, which come in Inside, Ocean View, Balcony and Suite categories. All include flat-screen TVs and minibars. Suites come with extra perks like butler service and bathtubs. Those looking for even more pampering can opt for Samsara category cabins, which offer exclusive access to the Samsara Restaurant and Samsara Spa.

As far as onboard entertainment goes, guests can enjoy shows in the three-story theater, dance at the disco or play games in the casino. Cruisers also have access to 11 bars and lounges, duty-free shopping and three pools (one of which is equipped with a retractable glass roof).

Cruising clans will appreciate the family-friendly amenities like kids clubs, a baby pool and a water park, plus activities like laser tag and the Grand Prix Simulator. While some passengers reported a good experience overall, many noted that Diadema's public spaces can feel crowded and the service can be disappointing.

In 2019-20, Costa Diadema sails to destinations in the Mediterranean, like Barcelona, as well as Abu Dhabi and Dubai
