Mardi Gras: year-round from Port Canaveral, and short cruises from May 2027
Mardi Gras is the first ship in Carnival's Excel class: 180,800 gross tons, 344.4 metres by 41.7, eighteen decks of which eleven carry cabins, and 2,641 cabins in total. She sails with 5,270 guests at double occupancy — some technical sheets put the figure at 5,282 — and up to roughly 6,500 people when every upper berth and sofa bed is filled, with 1,735 crew. She was built at the Meyer Turku yard in Finland and is Carnival's first LNG-powered ship. Commercial service began on 31 July 2021, not in 2020 as several databases still show; that earlier year refers to the delivery of the hull. She is based at Port Canaveral, Florida, year-round.
What changes in May 2027, and why it matters now
Carnival confirmed in August 2025 that Mardi Gras will become the first Excel-class ship to sell short cruises. The last three 7-night sailings leave Port Canaveral on 1, 8 and 15 May 2027. From 22 May 2027 the ship introduces a 5-night format calling at Celebration Key, RelaxAway Half Moon Cay and Nassau. On 27 May 2027 a 4-night format joins it, running to Celebration Key and Half Moon Cay. Anyone who wants a full week aboard the biggest ship at Port Canaveral is working against a window that closes in the spring of 2027.
Six zones instead of one long shopping promenade
The layout is the real argument for this ship. Rather than the single corridor that runs through older Carnival vessels, Mardi Gras breaks into six named districts, each with its own mood, bars and dining: French Quarter, Grand Central, La Piazza, Summer Landing, Lido and The Ultimate Playground. The crowd spreads out across them rather than piling into one place. On the top deck, BOLT remains the first genuine roller coaster ever fitted to a cruise ship, on an electric motorcycle whose acceleration you control yourself. It costs extra, has to be reserved, and shuts down as soon as the wind picks up.
A ship fresh out of drydock, not one waiting for a refit
In October 2025 Mardi Gras completed a full drydock in Marseille. The casino was enlarged, the shops redone, the Carnival Adventures desk redesigned and accessibility improved for guests with reduced mobility. The detail that actually matters to families: about one hundred connecting doors were added between cabins. They let six or eight people sleep side by side without moving up to a suite, and they sell out early for spring break.
Where to sleep, and what to avoid
Family Harbor cabins include private lounge access and come in layouts for four or five. Havana cabins open onto an area reserved during daytime hours for their occupants alone. Excel suites carry the key to Loft 19, the rooftop sun deck with cabanas. Whatever you choose, stay away from cabins directly under the pool deck or beneath the BOLT track: the noise starts before breakfast and runs all day.
What six thousand people do to a sea day
The space-to-guest ratio on Mardi Gras is tight, and guest reviews confirm it season after season. Elevators are besieged around 8 a.m. and 7 p.m., the Lido Marketplace buffet backs up at midday on sea days, and loungers are claimed early. The adults-only Serenity deck is frequently called windy. The main dining room is described as uneven from one night to the next. None of this is disqualifying, but a good week on board means booking dinner in the app and eating at off-peak hours.
Who this ship is wrong for
It is wrong for the traveller who wants quiet corridors, a calm pool and dinner without a reservation. It is equally wrong for anyone hoping to discover unusual ports: the calls stay squarely in the mainstream Caribbean, including Celebration Key, the private destination Carnival opened on Grand Bahama on 19 July 2025. From Montréal, plan on a flight to Orlando and about an hour's drive to the terminal, and sleep nearby the night before. A missed connection on embarkation morning cannot be recovered.
Before you settle on Mardi Gras
Carnival Celebration repeats the same zoned layout but sails from Miami on 6-, 7- and 8-night rotations; the 8-night departures add San Juan and St. Thomas, two calls the Port Canaveral schedule never includes. Carnival Firenze argues the opposite case: a former Costa ship with Italian interiors, no roller coaster and 4,126 guests rather than 5,270. Carnival Tropicale will sail from Galveston beginning with the 2028-29 inaugural season and will trade BOLT for Sunsation Point, a water park spread over several decks.
