History

  • 2014: Année de construction

The most accessible ship in the fleet

The Costa Diadema was delivered in October 2014 and named in Genoa the following month. 306 metres, fourteen decks, 1886 cabins, 3724 travellers at double occupancy. She is the largest ship ever built in Italy for Costa.

And above all she is the ship with the most wheelchair-accessible cabins: thirty-six, according to the third-party databases that derive them from deck plans. The figure is indicative, but the gap with the other ships is clear enough to guide a choice.

What you find nowhere else at Costa

She is the only ship in the fleet offering recessed balcony cabins, set low in the hull, close to the water and sheltered from the wind. It is not a panoramic balcony: the view is partly closed by the structure. It is a different object.

About half the cabins have a balcony, an outdoor promenade circles the ship, and the spa occupies four decks. Last refit in November 2023. Mediterranean and Baltic in summer, South America from late 2026.

The other ships in the fleet

The Costa Smeralda and the Costa Toscana are the two liquefied natural gas ships. The Costa Serena leaves for South America on a long crossing. The Costa Deliziosa has the highest proportion of cabins with a balcony.

The house, the group and the wreck

A Genoese house of 1854, come from olive oil and textiles, a shipowner since 1924, a carrier of passengers since 1947. An American group acquired half of it in 1997 and all of it in 2000; it is one of nine cruise brands there.

The fact that matters today lies elsewhere: the fleet went from sixteen ships in 2019 to eight in September 2026. Seven hulls sold or transferred, one scrapped. That is half a company gone in six years, and it shows on our own site, where nine pages out of seventeen describe a ship that is no longer there.

On 13 January 2012 the Costa Concordia struck rocks off the island of Giglio with 4252 people aboard. Thirty-three people died, including a diver killed during the salvage. The captain was sentenced to sixteen years, upheld on final appeal. We say it here because a client will read it elsewhere, and it is better read accurately.

The fare in detail

Included are the cabin, board in the main restaurants and the buffet, shows, activities, the children's club and port taxes. Excluded are the flight, insurance, drinks outside meals, excursions, speciality restaurants, treatments and laundry.

The hotel service charge is the item to explain before booking, not after. It is added to your onboard account each day, the contract calls it mandatory, and the sums are shared among the staff. It varies with age and with region. You may ask for it to be adjusted at the front desk, but only while you are aboard.

On drinks, a package exists and is bought in advance or aboard. Without one, every drink goes on the account. The Italian coffee is excellent and it is paid for, which often surprises a North American traveller used to free filter coffee at the buffet.

Aboard, and for whom

Costa is excellent for a Europe-loving traveller who wants to be in Europe the moment they board, who dines late, who goes ashore every day and who uses the ship as a hotel. Costa suits badly a first-time cruiser comparing with the big North American lines: they will be disappointed by the daytime programme and unsettled by the multilingual announcements.

The concrete points. Announcements run through several languages in turn. The evening buffet follows European hours. Smoking is tolerated more widely than here. Service is more distant, less chatty. In exchange, the crew amounts to roughly one person for every three travellers and the excursion catalogue is among the largest in the business.

Accessibility, finally. No official table of adapted cabins is published ship by ship. The circulating figures are derived from deck plans by third-party databases: indicative, never contractual. A wheelchair booking is validated with the line, cabin by cabin.

What this trip asks of you from Quebec

A flight not included in the fare, a hotel night before embarkation that we recommend every time, and a valid passport. Door-to-door travel often exceeds what the brochure suggests, especially when the embarkation port needs a connection.

The recourse question comes up weekly with clients. The carrier is a company under Italian law; the North American entity is only its sales agent. The contract provides for Italian law, the courts of Genoa to the exclusion of all others, and the Athens Convention, which caps liability for personal injury.

Quebec protection comes from the agency that sells. Nothing establishes a Quebec licence in the line's name. Voyages AquaTerra holds a licence from Quebec's Office de la protection du consommateur, deposits your payments in a trust account, and your file falls under the Compensation Fund for Customers of Travel Agents.

Frequently Asked Questions

Thirty-six according to third-party databases derived from deck plans, the highest number in the fleet. The figure is indicative and not contractual: the line publishes no official table. Have the cabin validated before a deposit.
A balcony set low in the hull, close to the water, sheltered from the wind. This ship is the only one in the fleet to offer them. The view is partly closed by the structure: it is not a panoramic balcony, it is a different object.
Three thousand seven hundred and twenty-four at double occupancy, in 1886 cabins. The maximum capacity the line publishes is far higher, because it counts third and fourth berths.
No, about half. That is markedly better than on the fleet's most common class of four ships, where fewer than forty per cent have one and nearly forty per cent are inside cabins.
October 2014, with a naming in Genoa the following month. She measures 306 metres and is the largest ship ever built in Italy for this line. Last refit in November 2023.
The group redeploys its hulls to the markets it judges most profitable. Three Costa ships were transferred to the group's North American brand, and the stake in the Chinese joint venture was sold in 2023.
Yes. The hotel service charge is not included in the cruise fare: it is added to the onboard account each day and the contract calls it mandatory. Budget for it from the start.
The cabin, meals in the main restaurants and the buffet, evening shows, entertainment, the children's club and port taxes. Not the flight, not insurance, not drinks outside meals, not excursions.
The Mediterranean and the Baltic in summer, out of Kiel and Copenhagen, then South America from late 2026 with repositioning crossings. Two hundred and thirteen departure dates sit with us.
The line publishes no official table of adapted cabins, ship by ship. The circulating numbers come from third-party databases derived from deck plans: indicative and never contractual. Have the cabin validated before paying a deposit.
An international convention invoked in the contract of passage which caps the carrier's liability for personal injury. It applies to most European cruise operators, not only to this one.
It depends on the ground. Few on European itineraries, markedly more in the Caribbean and South America. It is a real nuance: the atmosphere aboard changes with the season and the region.
Yes, more than five hundred metres, circling the ship. It is a feature that matters more than people think on a crossing, when there is no call for several days running.
Summer for the Baltic and the Mediterranean, the southern summer for South America. The autumn repositioning crossings suit anyone who likes long days at sea and low-season fares.
It applies in the situations set out in Quebec's travel agents legislation, notably a supplier's insolvency. The cover has defined limits and does not replace travel insurance.
