The Best Royal Caribbean Ships for Adults

Royal Caribbean isn’t just for kids – and some ships are far better for adults than others.

While the cruise line is famous for family-friendly fun, it also offers plenty for grown-ups who want a more relaxed, more sophisticated cruise. Think adults-only solariums, late-night bars, casinos and nightlife that doesn’t wind down early.

The catch? Not every ship delivers the same experience. Some feel busy and high-energy, while others are much better suited to adults who want space, calm, or evenings that last a little longer.

So which Royal Caribbean ships really get it right for adults?

Don’t Expect Adults-Only Cruises

With 29 ships in the fleet, Royal Caribbean does not have any cruises that are for adults only – families are always welcome. Anyone looking for a Royal Caribbean adults-only cruise will have to content themselves with the dedicated spaces onboard ships where kids are excluded.

You can definitely have a great time on an adults-only getaway with Royal Caribbean, just don’t expect a ship completely free of children.

There’s Always an Adults-Only Section

Every Royal Caribbean ship has adult-only areas. These include the solarium, casino, nightclub, spa and certain adult-only bars and lounges.

1. Solarium – This is featured on all Royal Caribbean ships and is only open to guests aged 16+. The venue has pools, whirlpools, a bar and some ships also have a cafe.
2. Casino – All Royal Caribbean ships have a casino, and guests must be 18+ to enter. Any adults are able to visit, even if they are not gambling, as there is a bar and seating in most.
3. Nightclub – Every Royal Caribbean cruise ship offers a nightclub space on board for adults to enjoy music and dancing into the early hours.
4. Spa – Each ship in the Royal Caribbean fleet has a spa with treatments including facials, acupuncture and massages. A kid-free venue, it offers the ideal sanctuary for relaxation.
5. Bars and lounges – These are included in every Royal Caribbean ship and are great for trying out cocktails, listening to live music and meeting friends over an after-dinner drink.

The Best Royal Caribbean Ships for Young Adults

The best Royal Caribbean ships for younger adults are the Quantum-class ships. While this isn’t the biggest class for Royal Caribbean, its onboard facilities are more focused on technology, adrenaline-rushing activities and thrill-seeking, with plenty of adult-only options too.

Royal Caribbean’s Quantum-class ships feature the cruise line’s first installations of the North Star observation pod and the RipCord by iFLY skydiving simulator.

You can enjoy cocktails crafted by robots, fantastic stage shows and watch the cruise industry’s best cover bands at the Music Hall.

The Best Royal Caribbean Ships for Couples

The best class of Royal Caribbean ships for couples is the Quantum Ultra Class. Just a step up from the Quantum Class, these ships pack even more on-board to keep both you and your partner entertained, including the lively Lime & Coconut Bar, Playmakers Sports Bar, laser tag and more!

Spectrum of the Seas is mainly based in Asia, featuring regional flavours on menus in restaurants such as Sichuan Red and Noodle Bar, while Odyssey of the Seas is found in the Mediterranean and Caribbean.

The modern and innovative ships feature two open-air, resort-style pools for optimal fun in the sun, alongside the first fully-immersive, 4D virtual reality experience at sea – Virtual Adventure Zone.

The Best Royal Caribbean Ships for Seniors

The Radiance Class is best for seniors as it offers a smaller ship experience, alongside all the signature features cruisers of Royal Caribbean come to expect. These ships don’t tend to attract as many crowds or young families, meaning they’re quieter and more relaxed. 

Radiance-class ships offer floor-to-ceiling views – perfect for taking in the sunsets and watching your destinations come into view. With destination-focused itineraries, you can enjoy more time ashore and fewer sea days than on the larger ships.

If your priority is peace and space rather than onboard attractions, Radiance-class ships are the best choice in the fleet.

The Best Royal Caribbean Ships for Solo Travellers

Royal Caribbean’s Oasis Class is best for solo travellers, as those travelling alone couldn’t possibly get bored while sailing on some of the largest cruise ships in the world! With a variety of activities and entertainment for all tastes and ages, these ships are ideal for making newfound friends and enjoying plenty of experiences while you sail.

Ships in the Oasis Class include Oasis, Allure, Harmony, Symphony and Wonder of the Seas. There is a larger class of ship now available, too – the Icon Class. So that’s another option if you want an epic action-packed experience.

The Oasis-class ships are well-known for a few things. Central Park is a popular venue which is situated in the centre of the ship and brings a neighbourly vibe. With more than 10,000 plants and flowers, it’s a true tropical hideaway.

Other features of Oasis-class ships include the tallest slide at sea – the Ultimate Abyss – and the incredible AquaTheater stage for diving and acrobatics like you’ve never seen before.

The Best Overall Royal Caribbean Ships for Adults

The newest ships in the Royal Caribbean fleet are the Icon-class ships, with Icon of the Seas and Star of the Seas now jointly holding the title of the largest cruise ships in the world. A third sister ship, Legend of the Seas, is due to launch in 2026.

While the Icon Class is hugely popular with families, it’s also one of the best options for adults cruising without kids or anyone who wants a balance of excitement and relaxation. These ships are designed with clear “neighbourhoods”, making it easy to escape the busiest areas and find more grown-up spaces.

Adults looking to unwind will love Chill Island, home to multiple pools and bars, including Swim & Tonic, the first swim-up bar at sea, and Cloud 17, an adults-only pool area. The Lime & Coconut bars add a lively but relaxed atmosphere, with some venues specialising in frozen cocktails.

There’s also The Hideaway, a dedicated adults-only neighbourhood featuring a suspended infinity pool and tiered sun decks, offering one of the most relaxed spaces on any Royal Caribbean ship.

Beyond the adult-only areas, Icon-class ships offer a huge choice of dining, bars, lounges and evening entertainment, meaning adults can easily enjoy the ship long after the family-focused attractions have quietened down.

Recommendation

While Royal Caribbean doesn’t place an age limit on its sailings, there are still plenty of options for guests seeking an adult-only experience. Whether you’re taking a break from the kids while they play in the Adventure Ocean kids’ club, or you’re honeymooning as loved-up newlyweds, there are a few spots and venues where children aren’t to be seen.

The newer classes of ships are better catered to younger adults and those seeking adventure, while the smaller classes of ships bring with them more port-intensive itineraries as well as a pared-back roster of activities, meaning there will likely be fewer children around.
