The Mardi Gras cruise ship. LNG-powered fun ship expands Carnival portfolio

Mardi Gras cruise ship is not quiet when you stand at the rail and feel the warm Florida air hitting your face as the horn sounds out of Port Canaveral. The ship’s neon-lit atrium stretches above you, and somewhere overhead the Bolt roller coaster rattles on its track.

What kind of ship Mardi Gras is

Mardi Gras is a 180,000-gross-ton cruise ship operated by Carnival and built by Meyer Turku in Finland as the first vessel in Carnival’s Excel class, running on liquefied natural gas (LNG) instead of conventional heavy fuel oil. It entered service in 2021 and sails primarily from Port Canaveral on Caribbean itineraries with a capacity of roughly 5,200 guests based on double occupancy.

Christine Duffy, president of Carnival Cruise Line, has repeatedly highlighted that Mardi Gras’s LNG propulsion and size are central to the brand’s strategy of combining lower emissions with what she calls “fun” hardware for family guests. The ship’s name revives the original Carnival vessel from the 1970s, connecting the newest hardware with the company’s heritage narrative.

Onboard experience from dining to Bolt

One of the main talking points on Mardi Gras is the Bolt roller coaster mounted on the upper deck, a two-person electric vehicle on a track that lets guests race above the ship’s sports complex at up to 40 miles per hour, paying per ride rather than per day. Reviewers who have tested Bolt describe the wind whipping around their ears and the brief pull of acceleration as they curve around the funnel, with views over the ocean far below.

The ship is structured into six themed zones including Grand Central, French Quarter and the Ultimate Playground, each combining bars, entertainment and dining tailored to different demographics. Grand Central houses a three-deck atrium with floor-to-ceiling windows facing the sea, turning into a performance space at night, while French Quarter features venues with New Orleans-inspired décor and music.

LNG, emissions and engineering choices

LNG propulsion is central to Mardi Gras’s engineering profile, with the ship using dual-fuel engines that can run on both LNG and conventional fuel depending on availability, contributing to lower sulfur emissions and reduced particulate matter compared to older tonnage. Carnival positions this hardware as a step toward meeting tighter regulations in coastal emission control areas and port cities.

From a design perspective, the LNG installation required Carnival and Meyer Turku to allocate more space for cryogenic tanks and fuel-handling equipment, affecting internal volume and layout compared to similar-tonnage ships using conventional fuel. Engineers had to balance this with guest-facing areas, ensuring that public spaces such as the Grand Central atrium retained the open feel that the marketing material promises.

Cabins, target guests and revenue logic

Mardi Gras’s accommodation mix ranges from standard inside cabins up to Excel suites with direct access to the Loft 19 sun deck, targeting a blend of budget-conscious families and higher-yield guests who value privacy and dedicated service. Carnival’s booking data suggests that the Excel suites and specialty restaurants such as Rudi’s Seagrill and Emeril’s Bistro 1396 generate incremental onboard revenue beyond base fare.

David Bernstein, chief financial officer at Carnival Corp. & PLC, has argued on investor calls that large Excel-class vessels like Mardi Gras are designed specifically to increase onboard spend per passenger day through attractions, branded food outlets and targeted bar concepts rather than relying solely on ticket price. That includes the pay-per-ride Bolt roller coaster, specialty dining surcharges and tiered Wi-Fi packages marketed as “Premium” and “Plus”, extending monetization across the voyage.

Port Canaveral and deployment patterns

Mardi Gras is based year-round at Port Canaveral, one of the busiest cruise ports in the world, chosen by Carnival for its proximity to Orlando and the flow of drive-to and fly-to guests from North America. The ship’s itineraries include seven-day Eastern and Western Caribbean routes that call at destinations such as Cozumel, Costa Maya and the company’s private destination on Grand Turk.

The homeport choice also aligns with LNG bunkering infrastructure: Port Canaveral has LNG fueling capacity developed in coordination with Carnival and gas suppliers, which supports regular refueling schedules for Mardi Gras’s operations. That infrastructure is still not common at every cruise port, limiting where LNG-powered ships can be deployed over the medium term.

Safety, operations and crew

Operating a ship of Mardi Gras’s scale requires a crew counted in the thousands, covering hotel functions, deck and engine departments, entertainment and technical support. Carnival’s recruitment materials point to specific training for LNG handling and emergency procedures for crew in the engine department and bridge team, as LNG is stored at extremely low temperatures and must be managed carefully.

Reviews from maritime classification societies and flag authorities show that Mardi Gras meets current international safety standards under SOLAS and MARPOL, with audits covering fire safety, lifesaving appliances and pollution prevention. Guests encounter these standards in visible ways through muster drills, signage and safety briefings before departure, although most of the compliance work happens behind doors in control rooms and at design stage.

Pricing and booking dynamics

Mardi Gras’s pricing structure fluctuates based on seasonality, cabin type and promotional campaigns, with seven-night Caribbean itineraries often starting in the region of several hundred US dollars per person for interior cabins when booked in advance. Higher-tier suites with Loft 19 access command significantly higher fares, especially in peak holiday periods when demand is strongest.

Online booking platforms and Carnival’s own booking engine indicate that families with children and multigenerational groups are key segments, often booking multiple cabins or larger staterooms such as Family Harbor accommodations with dedicated lounge access. These segments typically spend more on shore excursions and onboard activities, feeding into the revenue logic that David Bernstein outlined for the Excel class.

Competitive position and Carnival stock

Within the broader cruise market, Mardi Gras competes with similarly sized ships from Royal Caribbean and MSC Cruises that also emphasize attractions, large open spaces and branded dining concepts. Carnival’s choice to adopt LNG and introduce Bolt gives the ship distinguishing features, even though the core product remains a week-long leisure cruise combining Caribbean ports with a dense onboard entertainment program.

As a fleet asset, Mardi Gras is one of the hardware pillars supporting Carnival Corp. & PLC’s capacity recovery and onboard revenue drive after the pandemic, and the Carnival Corp. & PLC stock on the New York Stock Exchange reflects investors’ expectations around how efficiently ships like Mardi Gras can be filled and monetized.
