Quietest cabins on Carnival Mardi Gras

Carnival Mardi Gras is an Excel-class ship with 19 decks, 11 of them with cabins, and 2,641 staterooms. She entered service in 2021 and was refitted in October 2025. The ship is laid out in six themed zones: Grand Central, the French Quarter, La Piazza, Summer Landing, the Lido, and the Ultimate Playground. There is no Deck 13. The quietest rooms are the midship cabins on Decks 10, 11, 12 and 14, sandwiched between cabin decks. The noisiest are on Deck 15, directly below the Lido pool deck and buffet, on Deck 5, directly below the Deck 6 theater and bars, on Deck 8, directly above the theater, and on Deck 17, directly below Serenity.

Rate a cabin on this ship

The short answer

Quietest: midship cabins on Decks 10, 11, 12 and 14. Cabins above and below, no public venue on either neighbouring deck.
Also quiet: the forward half of Deck 9, above the Deck 8 Havana cabins, the forward Deck 15 cabins below the Deck 16 cabins, and the Deck 16 forward cabins.
Check before booking: Deck 15 below the Lido deck and buffet, Deck 5 below the Deck 6 theater and bars, Deck 8 above the theater and beside the Havana Bar, Deck 17 below Serenity, and the Deck 4 cabins beside Camp Ocean.
No cabin on Mardi Gras scores below C. The noisiest spots each carry one strong adjacency, never two stacked ones, and the ship has no cabins beside the engine room.
No cabin sits below the BOLT roller coaster. It runs around the aft end of Deck 19, above the Ultimate Playground, and Decks 16 and 17 have cabins only forward.

How Carnival numbers its cabins

Carnival numbers cabins differently from Norwegian Cruise Line, so read the number this way. The leading digits are the deck: 9201 is Deck 9, 15201 is Deck 15. Even numbers are port side and odd numbers are starboard side, for every cabin including insides. Numbers increase from forward to aft, so the lowest numbers on a deck are the forward-most cabins and the highest are the aft-most. No digit tells you whether a cabin is inside, oceanview or balcony: inside cabins take numbers from the same fore-to-aft sequence as the outside cabins on their side. Deck 5 starts at 5202, because the Cloud 9 Spa occupies the forward-starboard corner where 5201 would be.

The noise vectors on this ship

Every rating on Mardi Gras comes from one or more of these. They are the same vectors we grade on every ship, so grades stay comparable.

Pool deck above (Deck 15)

Deck 16 is the Lido deck: the Beach Pool midship, the Lido Marketplace buffet midship and aft, the Tides Pool aft, plus the RedFrog Tiki Bar, the Seaside Theater outdoor screen and Big Chicken. Every cabin on Deck 15 aft of 15297 sits below some part of it. The buffet stretch is the worst for early risers, because kitchen setup starts before breakfast and late night snacks run until 1 am. The pool stretch brings morning chair setup and daytime pool activity. The forward Deck 15 cabins escape all of it, because Deck 16 is cabins, not pool deck, at the forward end.

Serenity above (Deck 17)

Deck 18 forward holds Serenity, the adults-only retreat, with a pool, whirlpools, a bar and loungers, and LOFT 19 above that. Every cabin on Deck 17 sits below it. These are all Cloud 9 Spa cabins and suites, including the two Excel Presidential Suites. Expect deck noise overhead early and late, including evening dance parties. There is no quiet spa cabin on this ship: the Deck 5 spa cabins sit below the theater instead.

Theater below (Deck 8) and above (Deck 5)

The Mardi Gras Theater spans Decks 6 and 7 at the forward end. The Deck 8 Havana cabins sit directly above it, and the Deck 5 forward cabins sit directly below it. Amplified shows run most evenings, and bass carries through the deck in both directions. The Deck 8 cabins above the stage end hear the most. The theater is quiet during the day.

Public deck above (Deck 5)

Deck 6 is the ship's busiest public deck: the theater, the Punchliner Comedy Club, Piano Bar 88, the Grand Central atrium, the French Quarter restaurants and bars, and the shops. Every cabin on Deck 5 sits below some part of it. The theater, comedy club and atrium stretches are the worst, because those venues run amplified shows into the night. The restaurant stretch, aft, is the gentlest, with daytime footfall and evening service noise but no show venue.

Grand Central (Decks 5 and 9)

Grand Central is the ship's three-deck atrium on Decks 6, 7 and 8, midship, with a stage for live entertainment, 16 LED screens, lasers and aerial feats. The Deck 5 cabins below it and the Deck 9 cabins above it both hear the shows. The atrium is the loudest venue on the ship after the theater, and it runs most nights.

Havana Bar (Decks 8 and 9)

The Havana Bar sits forward on Deck 8, at the aft end of the Havana cabin block, with live Latin music in the evenings. After midnight it becomes a Latin disco club. The Deck 8 cabins beside it, 8286 to 8305, hear the music through the wall, and the Deck 9 cabins above it, 9319 to 9329, hear it through the floor. The bar is the latest-running noise source on the ship.

Summer Landing below (Deck 9 aft)

Summer Landing is the aft outdoor area on Deck 8, with live music nightly at Guy's Pig and Anchor Smokehouse, the Watering Hole bar, a pool and whirlpools. The Deck 9 aft cabins sit directly above it. The music is outdoors, but the stage sits right below these balconies.

Kids clubs beside (Deck 4)

Camp Ocean and the Family Harbor Lounge sit midship on Deck 4, sharing a corridor with the 4311 to 4369 cabins. The noise is daytime: kids programs, drop-off and pick-up traffic. Night Owls babysitting runs until 1 am. Families using the clubs may count the location as a plus.

Anchor and thrusters (Deck 4 forward)

The forward-most cabins on Deck 4 sit closest to the bow, where the anchor windlass and bow thrusters live. Expect anchor chain noise and a low thruster rumble on port mornings, when the ship docks. It is brief and tied to port days, not a nightly problem.

Lowest cabin deck (Deck 4)

Deck 4 is the lowest deck with cabins, above crew and service areas and closer to the ship's machinery spaces than any higher deck. The effect is a low background hum rather than a specific noise event, and it is mildest midship.

Best and worst zones

Best for sleep: a midship balcony or inside cabin on Deck 11 or 12. Cabins above and below, no venue on either neighbouring deck, and midship means the least motion in rough seas.

Best for families with small children: the Deck 4 cabins beside Camp Ocean, 4311-4369. The daytime noise is the trade for being steps from drop-off, and the clubs close in the evening except for Night Owls.

Best for spa lovers: the Cloud 9 Spa cabins on Deck 17, 17201-17293, with Serenity overhead as the trade. The Deck 5 spa cabins sit below the theater instead, so pick by which noise bothers you less.

Worst for light sleepers: the Deck 8 cabins beside the Havana Bar, 8286-8305. They carry a late-night disco beside them and the casino below, and the bar runs past midnight.

Worst for late risers: the Deck 15 midship cabins below the pool deck and buffet, 15298-15455. Morning chair setup on the pool deck and buffet setup start early.

Why there are no decibel numbers here

The Quiet Index is not a sound meter

Every grade on this page comes from the deck plan alone: what sits above, below and beside each cabin. The site publishes no decibel figures, because a single sound reading in one cabin on one night would not describe that cabin on any other night, and it would say nothing about the cabin next door. A deck plan position is permanent. A reading is a snapshot.

That is the honest limit of this guide, and also its strength. The adjacencies do not change between sailings. If a cabin sits below the pool deck, it sits below the pool deck on every cruise. Grade the position, and the risk travels with it.
