Royal Caribbean vs. Carnival: Which big-ship cruise line should you choose?
If you're considering a cruise with Royal Caribbean or Carnival Cruise Line, you're looking at a big-ship experience with lots of activities.
These two companies are the largest in the cruise industry, each with two dozen ships carrying millions of passengers a year. They are popular for a reason: Their ships offer something for everyone, from kids to seniors.
Let's go head-to-head, Carnival versus Royal Caribbean, to highlight their similarities and differences and help you choose the line that's right for you.
Size of ships
Both Carnival Cruise Line and Royal Caribbean have two sizes of megaships. Their smaller ships carry 3,000 to 4,000 passengers; their larger ones are huge, carrying more than 5,000 guests. Royal Caribbean wins the battle of size, with seven of the world's largest ships — including Icon of the Seas and Utopia of the Seas, the two largest cruise ships afloat.

Royal Caribbean's largest classes — Oasis Class and Icon Class — are so big that they are divided into neighborhoods. Ships in both of these classes feature a Central Park with real trees and a special theater for high-diving shows. Oasis Class ships each have a Boardwalk area with a carousel and a slide that drops multiple decks. Icon Class ships have separate sections for young families, thrill seekers and adults looking for a beach club scene.
Not to be outdone, Carnival's largest ships — Mardi Gras, Carnival Celebration and Carnival Jubilee — are divided into zones, such as Mardi Gras' French Quarter with a live jazz club.
No matter the size, all the ships of both lines qualify as floating resorts, with onboard casinos, pools, live entertainment, elaborate spas, lively dance clubs, lots of bars and, yes, crowds.

Cabins and suites
Both lines cite with pride their price range for all vacationers, but you'll notice each excels in a different accommodation area.
Royal Caribbean is a better option if you want a huge selection of cabin categories. The cruise line offers everything from tight inside cabins with virtual balconies (an LED screen that looks like the ocean) to fancy two-story loft suites. Its largest ships have the most room choices, and you can book suites with views of the high-diving show or the ships' Royal Promenade, Central Park or Boardwalk areas. The soothing decor is like a Marriott or Hilton hotel, nice and slightly upscale.

Carnival wins for the size of its standard cabins, which are the largest in the industry. The decor is typically bright and casual. Specialty cabins on select ships include Family Harbor cabins, with access to a shared family lounge, and Havana suites, with daytime access to a private pool area. The newest ships have more suites than earlier vessels.

Food and drink
When looking at dining options on Royal Caribbean versus Carnival, Carnival has the edge for abundant included offerings, and Royal Caribbean leads with its number of extra-fee specialty restaurants.
Carnival fans will tell you the food on board is great, and most travel writers will agree the line shines in this area — including extra-fee options, such as impressive steakhouses and JiJi for Asian cuisine. Carnival's lineup of free eats is extensive — headlined by poolside burgers by Food Network star Guy Fieri but also including Mexican, barbecue, excellent Italian-style pizza and Shaquille O'Neal's fried chicken.
If you like Indian cuisine, you are in for a treat with delicious vegetarian dishes on the main dining room menu each night. On select ships, Carnival has its own New Orleans bistros by Emeril Lagasse and breweries where the drink is accompanied by Fieri's barbecue (for a fee).

Most of Royal Caribbean's free food is found in its Windjammer Marketplace (the buffet) and main dining rooms, again focusing on typical hotel cuisine. Ships offer a variety of extra-fee restaurants, with specialties ranging from sushi to steak.
Shining stars among these alternative venues are Jamie's Italian, in partnership with British celebrity chef Jamie Oliver, and The Mason Jar, for tummy-filling Southern comfort food. You also can pay for a burger and a milkshake at Johnny Rockets on some of Royal Caribbean's larger ships.
More experiential dining options include Royal Railway — Utopia Station, which delivers a family-friendly immersive "eatertainment" experience in a vintage-style train car on Utopia of the Seas. Special sound and visual effects transport diners to the Wild West (with a little onboard hijinks along the way). Or, if an exclusive 1930s-inspired supper club is your vibe, book a table at the Empire Supper Club (on Icon of the Seas) or the Lincoln Park Supper Club (on Star of the Seas, launching in August 2025).

Kids activities
Both cruise lines have well-established programs to keep your kids happy, so you can get some downtime to relax and do grown-up things. Both lines host more than a million children a year. The complimentary camplike programs include age-appropriate activities like arts and crafts, movies, sports and cool clubs for tweens and teens.
Royal Caribbean's Adventure Ocean program (for ages 3 to 12) features expansive kids clubs with spaces for art, video games, active play, theatrical productions and science experiments. Additionally, themed parties, nightly discos and scheduled sports activities provide tweens and teens with lively ways to connect with their peers in their own onboard hangout or around the ship. The Royal Babies & Tots Nursery (called "AO Babies" on some ships) is a fun space for the youngest cruisers, offering age-appropriate toys and activities led by certified child care specialists.
Carnival's Camp Ocean program (for ages 2 to 11) includes some activities designed to educate kids about the ocean. Carnival also has a partnership with Dr. Seuss that encourages children to read classic books. Kids can get to know the characters in a participatory parade, during story times and at an extra-fee Green Eggs and Ham Breakfast hosted by the Cat in the Hat. Tweens and teens have separate lounges with video games, comfy seating and versatile spaces for games or dancing.

Onboard attractions
Active cruisers take note: Royal Caribbean is an innovative company and pushes the envelope on activities. All the cruise line's ships have rock climbing walls, and many have FlowRider surfing simulators.
Among the activity choices on various ships are ice skating, carousel rides, zip lining, miniature golf, laser tag, escape rooms, zipping down waterslides, simulated skydiving, flying down a 10-story thrill slide called Ultimate Abyss and riding in a mechanical arm that lifts a London Eye-style pod high above the ship for views, among other mind-blowing options. The larger the ship, the more onboard activities you'll find.
Carnival can't quite compete in this department, but its ships don't lack things to do. It's known for its WaterWorks water parks with multiple waterslides and splash areas for little kids, as well as for Bolt, the first roller coaster at sea (found only on Mardi Gras, Carnival Celebration and Carnival Jubilee).
On select ships, you will find outdoor ropes courses where you can walk a plank off the ship (while in a harness), a top-deck ride involving pedaling a hanging recumbent bike, miniature golf, Imax theaters and even an indoor trampoline park.

Entertainment
Royal Caribbean and Carnival also take different approaches to onboard entertainment, though you'll never be bored on either line.
Royal Caribbean produces real Broadway shows (albeit shortened versions), such as "Grease," "Hairspray" and "Cats," on some of its biggest ships. Select ships feature innovative performance spaces; you'll find outdoor shows starring acrobats and high-divers at the line's AquaTheaters and ice skating shows at its ice skating rinks.
Multimedia shows in high-tech Two70 theaters on the Quantum Class ships feature performers and robotics. The Boleros salsa dance club is a popular late-night hangout spot. Don't miss the themed parades that take place on the Royal Promenade.
Carnival also excels at live entertainment, but its style is different from Royal Caribbean's. Instead of Broadway musicals, it offers 35- to 45-minute high-tech Playlist Productions, featuring singers and dancers performing to original compilations of familiar tunes. Carnival puts a big emphasis on comedy; the line's Punchliner Comedy Clubs host more than 27,000 live performances a year, which makes Carnival the largest employer of comics in the world.
Carnival also puts together its own live bands and musical acts — whether jazz, rock 'n' roll, show band or classical — that entertain at various bars and public areas throughout its ships.
Both lines offer a roster of games and contests (think: "Battle of the Sexes," the "Newly (and Not So Newly)wed Game" and some version of an adult scavenger hunt), and Carnival has shipboard versions of the popular show "Family Feud." It's also known for audience participation games around the pool and rollicking music trivia.

Who is on board?
Carnival's focus is affordable contemporary cruising for everyone, with an emphasis on fun. Its "Fun Ships" provide a casual and carefree experience; the crowd consists mostly of American, young and young-at-heart adults and their families. A lot of people come aboard looking for fun times — but don't think it's a haven for debauchery. It's still a family cruise line.
Since Carnival sails from many U.S. ports, you'll find that many cruisers on board hail from nearby states and have driven to the ship — meaning different ships can have different vibes and passenger bases.
Royal Caribbean's crowd is a mix of international travelers and those from North America, including couples, families and singles from all walks of life. You'll find night owls on Royal Caribbean, too, though the crowd is a tad more upscale and less rowdy than on Carnival. That's partly because Royal Caribbean ships have a higher percentage of expensive suites on board and attract travelers who can afford to pay for that type of luxury.
Itineraries
Carnival ships mostly cruise in North America, with voyages in the Caribbean, the Bahamas, Bermuda, Canada and New England, Alaska and the Mexican Riviera (from California). The line offers limited sailings in Europe.

Royal Caribbean puts much emphasis on North America — the Caribbean, the Bahamas (including the line's own extravagant private island, Perfect Day at CocoCay), Canada and New England, Alaska and the Mexican Riviera — but also sails several regions in Europe. Its ships can be found in other international destinations, such as Australia, New Zealand, Japan (sailing from China) and Singapore.
