What Cruise Ships Are Adult Only? A Complete Guide

Dreaming of a cruise where the loudest sound by the pool is the fizz of your cocktail, not a cannonball splash? An adult-only cruise might be exactly what you need. These sailings offer a sophisticated, serene, and decidedly grown-up atmosphere, perfect for couples, solo travelers, and groups of friends looking to relax and reconnect without any distractions.

But which cruise ships are adult only? The answer is more nuanced than you might think. While a few fantastic cruise lines are strictly 18+, many others offer incredible adult-focused alternatives. This guide will walk you through all your options for finding the perfect kid-free escape at sea.

Key Takeaways

* Truly 18+ Lines: [Virgin Voyages](/cruise-lines/virgin-voyages) and Viking are the two major cruise lines that are exclusively for adults, each offering a very different style of cruising.

* The "Almost" Adult-Only Experience: Luxury and expedition cruise lines like Silversea and Hurtigruten cater to a mature audience with itineraries and amenities that naturally result in very few, if any, children onboard.

* Best of Both Worlds: Most major family-friendly cruise lines, including [Royal Caribbean](/cruise-lines/royal-caribbean) and [MSC Cruises](/cruise-lines/msc-cruises), feature extensive adult-only zones, serene sundecks, and exclusive 'ship-within-a-ship' suite complexes.

* Guaranteed Atmosphere: Choosing a dedicated adult-only cruise line is the only way to guarantee a completely child-free environment throughout the entire ship, from the pools to the dining rooms and entertainment venues.

The Champions of Kid-Free Cruising: Truly Adult-Only Lines

If you want a 100% guarantee that your vacation will be child-free, booking with a strictly adult-only cruise line is the way to go. These lines design their entire experience—from the dining concepts to the entertainment—for a grown-up audience. The two leaders in this space offer distinctly different vibes.

Virgin Voyages: The Modern Rebel at Sea (18+)

[Virgin Voyages](/cruise-lines/virgin-voyages) has shaken up the cruise industry with its hip, modern, and slightly rebellious approach. Forget buffets and formal nights; think drag queen brunches, a tattoo parlor, and some of the best food at sea, all included in your fare. The vibe is energetic and youthful, attracting a crowd that's ready to have fun.

What sets Virgin apart is its incredible value. Your fare includes all 20+ eateries (no specialty dining upcharges), essential drinks (soda, water, drip coffee), Wi-Fi, all gratuities, and unlimited group fitness classes. Their ships, like the Scarlet Lady and Valiant Lady, are floating boutique hotels designed for socializing and relaxing in style.

Viking: Cultured Exploration for the Curious Traveler (18+)

On the other end of the spectrum is Viking. Known for its slogan "the thinking person's cruise," Viking offers a serene, destination-focused experience for travelers aged 18 and over. You won't find casinos or kids' clubs here. Instead, you'll find expansive libraries, resident historians, and cooking classes that reflect the region you're visiting.

Viking's ocean, river, and expedition ships are known for their clean Scandinavian design and inclusive value. Fares typically include one complimentary shore excursion in every port, Wi-Fi, and beer and wine with lunch and dinner. The atmosphere is quiet, cultured, and geared towards enrichment. For example, you could embark on a 6-day Great Lakes journey on the [Viking Octantis](/ships/viking-cruises/viking-octantis) from Milwaukee to Toronto. A sailing departing May 4, 2026, focuses on the history and geology of the region, attracting a mature and inquisitive crowd.

"Almost" Adult-Only: Lines with Very Few Children

Some cruise lines aren't officially 18+, but their itineraries, price points, and onboard focus mean you're highly unlikely to encounter many children. If you're comfortable with the small possibility of seeing a well-behaved teen at dinner, these lines offer fantastic adult-centric experiences.

Luxury Cruise Lines

Ultra-luxury lines like Silversea, Seabourn, and Regent Seven Seas cater almost exclusively to adults. Their ships are smaller, the service is exceptionally personal, and the focus is on fine dining, enrichment lectures, and immersive cultural experiences.

Due to the high cost, longer and more exotic itineraries, and lack of kid-specific amenities like water slides or arcades, very few families choose these lines for their vacation. An 11-day expedition cruise on the [Silver Endeavour](/ships/silversea-cruises/silver-endeavour) from Scotland to Iceland, for instance, is a journey centered on wildlife and dramatic landscapes, which naturally appeals to a more mature traveler.

Expedition and Exploration Cruises

Similar to luxury lines, expedition cruises are geared toward adventurous and curious adults. Companies like Hurtigruten (now HX) and Lindblad Expeditions sail to remote destinations like Antarctica, the Galapagos, and the Arctic.

The focus is squarely on learning and exploration, with daily lectures from scientists, naturalists, and historians. The onboard experience is comfortable but not flashy, as the destination is the star of the show. A journey like the 11-day Coastal Express Cruise on the [MS Richard With](/ships/hurtigruten/ms-richard-with), which makes dozens of stops along the Norwegian coast, is designed for scenic immersion, not family entertainment.

Finding Your Oasis: Adult-Only Spaces on Family-Friendly Ships

What if you want the thrilling amenities of a mega-ship—like Broadway shows, waterslides, and dozens of bars—but still crave a quiet place to escape? You're in luck. Most major cruise lines have invested heavily in creating serene, adult-only sanctuaries onboard their family-friendly ships.

Exclusive Suite Complexes (The 'Ship-within-a-Ship')

For the ultimate blend of big-ship energy and small-ship luxury, consider booking a suite in an exclusive complex. These private enclaves are accessible only by keycard and offer a completely different experience.

* MSC Yacht Club: Found on [MSC Cruises](/cruise-lines/msc-cruises) ships, this is arguably the best-in-class. It features a private lounge, restaurant, pool, and sundeck, plus 24-hour butler service. You get all the perks of a luxury cruise with access to the entire ship's entertainment.

* Norwegian's The Haven: A secluded complex with its own courtyard pool, restaurant, and lounge. Haven guests enjoy priority embarkation and entertainment seating.

* Royal Caribbean's Suite Class: While not a single physical location, suite guests on [Royal Caribbean](/cruise-lines/royal-caribbean) ships get access to an exclusive lounge, a dedicated restaurant (Coastal Kitchen), and a private sundeck on newer ships.

Serene Sanctuaries and Sundecks

Even if you're not in a suite, you can find your adult-only haven. Most large ships offer dedicated spaces for guests 16+ or 18+.

* Royal Caribbean's Solarium: A stunning, glass-enclosed, climate-controlled retreat with its own pool, whirlpools, bar, and comfortable loungers. It's a peaceful oasis regardless of the weather.

* Carnival's Serenity Adult-Only Retreat: A complimentary, open-air deck space with plush daybeds, hammocks, whirlpools, and a private bar. It's the perfect spot to read a book and soak up the sun.

* Princess Cruises' The Sanctuary: A spa-inspired, extra-fee retreat where you can rent a plush lounger or private cabana. Attendants offer chilled towels, detox water, and a special menu of light bites.

How to Choose the Right Adult-Focused Cruise

With so many options, how do you decide? It comes down to your personal vacation style, budget, and desired destinations.

What's Your Vacation Vibe?

* High-Energy & Social: If you want amazing nightlife, unique dining, and a party atmosphere, Virgin Voyages is your match.

* Quiet & Cultural: If you prefer enrichment lectures, scenic views, and early nights after a day of exploring, Viking is the perfect fit.

* Ultimate Luxury: For an all-inclusive, highly personalized, and pampered experience, look to luxury lines like Silversea or Seabourn.

* Big-Ship Fun, Private Escape: If you want access to rock climbing walls and Broadway shows but a quiet place to retreat, book a suite in the MSC Yacht Club or Norwegian's The Haven.

Consider Your Budget and Inclusions

The price of adult-focused cruises can vary widely. Mainstream lines with adult-only areas will have the lowest entry price. Virgin Voyages sits in a premium category, while Viking and the luxury lines represent a significant investment. However, always look at the total value. A higher upfront cost on Viking often includes flights, transfers, and excursions, which can make it more valuable than a cheaper cruise where you pay for everything a la carte.

Think About the Destination

Your destination can also guide your choice. Virgin Voyages excels in sunny destinations like the Caribbean and [Mediterranean cruises](/destinations/mediterranean). Viking covers the globe with a focus on culturally rich ports in Europe, Asia, and the Americas. Expedition lines, of course, are your ticket to the world's most remote and wild places.

Frequently Asked Questions About Adult-Only Cruises

Is there an age limit for adult-only cruises?

Yes. For cruise lines like Viking and Virgin Voyages, the minimum age to sail is 18. For adult-only areas on other ships, the age limit is typically 16, 18, or 21, depending on the cruise line and specific venue.

Are adult-only cruises more expensive?

They often fall into the premium or luxury categories, so their starting price can be higher than mass-market family lines. However, they frequently include more amenities like drinks, Wi-Fi, and gratuities, which can offer better overall value and a more stress-free vacation.

Can I find a quiet spot on a big family cruise ship?

Absolutely. The best strategies are to book a stateroom in an exclusive suite complex like the MSC Yacht Club or make frequent use of the dedicated adult-only areas like the Solarium on Royal Caribbean or the Serenity Deck on Carnival. These spaces are specifically designed to be peaceful retreats.
