Carnival Mardi Gras is a flagship-style Excel-class Carnival cruise ship with a warm, social personality and an onboard experience built around relaxed fun. Mardi Gras introduced Carnival's zone-based ship design, blending themed neighborhoods with big-ship attractions, modern staterooms, and the BOLT roller coaster at sea. Guests can start the morning with ocean views and an easy breakfast, spend the afternoon around the pool or activity decks, and move into an evening of music, comedy, shows, and late-night lounges without ever feeling like the vacation has to be formal. The ship is a strong fit for travelers who want a friendly, upbeat atmosphere with familiar comforts and plenty of ways to enjoy time at sea.

The onboard amenities give guests room to choose their own pace. BOLT, the Ultimate Playground, WaterWorks, pools, sports areas, Family Harbor, kids and teen spaces, Cloud 9 Spa, comedy, live music, and multiple themed zones create a destination-style ship experience. Active travelers can enjoy BOLT rides, waterslides, sports-deck time, mini-golf, fitness classes, and deck parties, while guests who want a slower rhythm can settle into Loft 19 for eligible guests, Serenity, Cloud 9 Spa, quieter bars, lounges, and ocean-view decks. Families will appreciate Family Harbor accommodations, Camp Ocean-style programming, family entertainment, casual dining, and kid-friendly outdoor spaces, and groups will like how easy it is for everyone to split up during the day and reconnect for dinner, comedy, music, or a show. That combination of open decks, casual hangouts, wellness options, and entertainment venues helps the ship feel like a complete floating resort.

Dining and evening energy are key parts of the appeal. Food is one of the ship's strongest selling points, with Emeril's Bistro, Big Chicken, Guy's Burger Joint, Cucina del Capitano, steakhouse dining, sushi, quick bites, and plenty of casual options. After dinner, the ship keeps the atmosphere lively with Center-stage performances, comedy, game-show style fun, live music, high-energy bars, casino gaming, and late-night lounges. Mardi Gras is built for guests who want the ship to be a major part of the vacation, with enough dining, activities, and entertainment to make every sea day feel full. Guests can expect comfortable accommodations, recognizable Carnival amenities, plenty of food and fun, and a vacation mood that stays upbeat from embarkation through the final morning.
