The best cruises for adults depend on how kid-free you want your vacation to be. If you want no children at all, look at Virgin Voyages, Viking, Explora-style luxury or, increasingly, Oceania. If you’re happy with a ship where kids are rare, luxury and premium lines such as Regent Seven Seas, Silversea, Azamara and Cunard work well. And if budget matters most, a family ship with a good adults-only zone can be the smartest buy.

This guide sorts the best cruises for adults into three practical groups, compares them in one table (minimum age, price level and vibe), and covers the policy changes for 2026 and 2027 that many older lists miss. If you only want lines that ban children outright, our separate guide to the best adults-only cruise lines goes deeper on that shortlist.
Three ways to cruise without kids
“Cruises for adults” can mean quite different things, and mixing them up is the most common reason people end up disappointed:
- Strictly adults-only lines: the cruise line sets a minimum age (usually 18) on every sailing. You will not meet a child on board.
- Adult-friendly lines: children are allowed, but the ships have few or no kids’ facilities, long port-intensive itineraries and higher fares, so very few families book. Outside school holidays you may not see a child all week.
- Adult zones on family ships: mainstream lines with water slides and kids’ clubs, plus adults-only pools, sun decks or retreats. You get big-ship variety and lower prices, but the rest of the ship is shared with families.

Strictly adults-only cruise lines
Virgin Voyages: best for a lively, social trip
Virgin Voyages is 18+ on every ship, including Scarlet Lady, Valiant Lady, Resilient Lady and Brilliant Lady. The fare covers all of the onboard restaurants (there is no traditional buffet or main dining room), basic drinks such as soft drinks and coffee, Wi-Fi and group fitness classes, and gratuities are built in. Expect DJ sets, cheeky late-night shows and a crowd that skews younger than most cruise lines. Caribbean sailings from Miami often call at the line’s Beach Club at Bimini, and the ships also sail Europe, Alaska and the Mexican Riviera. Alcohol is extra unless you buy a bar package.
Viking: best for culture and quiet
Viking’s ocean and river ships accept guests aged 18 and over only. The atmosphere is calm and grown-up: no casino, no kids’ club, no water park, and an emphasis on lectures, local food and port time. Fares typically include one shore excursion in each port, beer and wine with lunch and dinner, Wi-Fi and the Nordic-style spa’s thermal suite. It suits travelers who see the ship as a comfortable hotel between destinations rather than the destination itself.
Oceania Cruises: the newest adults-only line
The biggest change for 2026 is Oceania. The line announced that all reservations made on or after January 7, 2026 must be for guests aged 18 or over, across all eight ships. Bookings made before that date, including any with children, are honored, so you could still meet the odd family on sailings that were already on sale. Most commentators expect the policy to be fully felt from late 2027 into 2028. Oceania is best known for its cuisine, and it already attracted a mostly mature crowd.
Saga: best for over-50s from the UK
Saga’s booking conditions state that its cruises are for anyone aged 50 or over, with a travelling companion or family member allowed from age 40. Its small ships, Spirit of Discovery and Spirit of Adventure, sail from the UK and are all-inclusive, so drinks, tips and Wi-Fi are covered. It is a strong pick for British travelers who want a traditional, unhurried cruise; American travelers can book too, but most sailings start in Britain.
Adult-friendly cruise lines with very few kids
These lines don’t ban children, but their style, pricing and itineraries mean families are the exception. They are often the best cruises for adults who want luxury or a classic experience and don’t mind seeing a teenager by the pool now and then.
Regent Seven Seas and Silversea
Both are top-tier luxury lines with high space-per-guest and a lot included. Regent’s fares include drinks, specialty dining, gratuities and shore excursions; children aged one and over are accepted, and a youth programme runs on select school-holiday sailings. Silversea also accepts children but has no organized kids’ programme, which keeps it overwhelmingly adult. For both, avoid July, August and the Christmas weeks if you want the quietest ships.
Explora Journeys
Explora, MSC Group’s luxury brand, is all-suite and largely sells to couples. It is not adults-only: it runs a Nautilus Club for ages 6 to 17 and markets some sailings to multi-generational families. Outside school holidays, though, the onboard crowd is very much adult.
Azamara
Azamara’s small ships focus on longer stays in port, with late evenings and overnights in places like Barcelona or Lisbon. There is no kids’ club and children are uncommon, making it a good mid-priced alternative to the ultra-luxury lines.
Cunard
Cunard does carry families, with kids’ clubs on Queen Mary 2, Queen Victoria, Queen Anne and Queen Elizabeth. Even so, the gala evenings, ballroom dancing, afternoon tea and long voyages such as the transatlantic crossing tend to draw an older, adult crowd. A term-time transatlantic is one of the most grown-up experiences at sea.
Adults-only zones on family ships
If you want water slides, Broadway-style shows and lower prices, a mainstream ship with a good adult sanctuary can be excellent value:
- Celebrity Cruises: the glass-roofed Solarium is adults-only on most ships, and Celebrity attracts more couples than most big-ship lines.
- Princess Cruises: The Sanctuary is an adults-only, extra-cost retreat with loungers and cabanas, and the ships are generally calmer than other mega-ship lines.
- Royal Caribbean: every ship has an adults-only Solarium, and Icon-class ships add The Hideaway, an adults-only area with a suspended infinity pool.
- Carnival and Norwegian: Carnival’s Serenity retreat and Norwegian’s Spice H2O and Vibe Beach Club (on some ships) give you a kid-free place to sunbathe.
The trade-off: dining rooms, theaters and elevators are shared with everyone, and these ships are busiest during school vacations.
Budget and UK options for adults
The UK market has more adults-only choices than the US, and UK searches for “best cruises for adults” are far lower than in America, so these lines often fly under the radar for American readers. If you’re based in Britain, see our guide to adults-only cruises from the UK for departure ports and itineraries.
- P&O Cruises (Arcadia and Aurora): long known as adults-only ships, but P&O is opening selected sailings to all ages, starting on Aurora from December 11, 2026 and Arcadia from December 21, 2026 (20 family-open holidays through September 2027). Most of their year stays adults-only, so check the specific cruise code before booking.
- Marella Cruises: Marella Explorer 2 is adults-only year-round, with a minimum age of 17, and the fare includes meals, drinks and tips. Marella also switches other ships to adults-only for set seasons, such as Marella Discovery 2 for winter. Our guide to Marella adults-only cruises explains how it works.
- Fred. Olsen: Borealis is now adults-only, while Bolette and Balmoral welcome children from 12 months. From 2026 the Little Skippers kids’ clubs are no longer offered, so the whole fleet feels very grown-up.
- Ambassador Cruise Line: a budget-friendly, no-fly line sailing from ports such as Tilbury, Liverpool and Bristol. It describes itself as adult-only apart from a small number of multi-generational school-holiday cruises, and says all no-fly sailings will be adults-only from the 2027-2028 season.
How to choose the best cruise for adults
Once you know which group you want, a few simple choices make a bigger difference than the brand name:
- Decide how strict you need it to be. If a single toddler at dinner would spoil the trip, book a true 18+ line. If not, adult-friendly lines open up more itineraries.
- Avoid school holidays. Summer, Christmas, spring break and mid-term weeks bring families even to luxury lines. Late September to early December and January to early March are usually the most adult months.
- Pick longer or more unusual itineraries. Cruises of 10 nights or more, transatlantic crossings, repositioning voyages and port-heavy routes attract fewer families than three- or four-night Caribbean getaways.
- Price the extras. Viking, Regent, Saga and Marella include more than a mainstream fare, so a cheaper base price on a big ship may cost more once you add drinks, tips and Wi-Fi.
- Match the vibe. Night owls tend to prefer Virgin Voyages; food lovers Oceania; history buffs Viking; and classic cruisers Cunard or Saga. Solo travelers should also compare single supplements, which vary a lot between lines.
FAQs
What cruise lines are best for adults?
For a guaranteed child-free trip, Virgin Voyages, Viking and (for new bookings) Oceania are 18+. Regent Seven Seas, Silversea, Azamara and Cunard carry very few children, and Celebrity and Princess offer good adults-only spaces on family ships.
Which cruise lines are adults-only in 2027?
Virgin Voyages and Viking are 18+ on all sailings, Oceania requires guests to be 18+ for bookings made from January 7, 2026, and Saga is for over-50s. In the UK, Marella Explorer 2 and Fred. Olsen’s Borealis are adults-only, while P&O’s Arcadia and Aurora are adults-only on most but not all sailings.
What happens on adults-only cruises?
Much the same as any cruise, minus the kids’ clubs and water slides: dining, shows, spa time, lectures and shore excursions. The pace depends on the line, from Virgin Voyages’ late-night parties to Viking’s quiet, culture-focused days.
Is Celebrity Cruises good for adults?
Yes. Celebrity welcomes families, but it draws more couples than most big-ship lines and has an adults-only Solarium on most ships. Sailing outside school vacations keeps the number of children low.
What is the cheapest way to cruise without kids?
Book an adults-only zone on a mainstream ship outside school holidays, or in the UK look at Ambassador, Marella Explorer 2 or Fred. Olsen. Virgin Voyages can also be good value once its included dining, Wi-Fi and tips are taken into account.
