The cruise industry spent decades pricing solo travellers as a problem. Every cabin assumed two people, so travelling alone meant paying a “single supplement” — often the full second fare — for the privilege of an empty bed. A $1,200 week at sea quietly became $2,400 the moment you booked it for one.
That era is ending, unevenly. A handful of cruise lines now build cabins for one, price them for one, and run actual social programming so you board alone but don’t spend the week that way. Others still charge you double and hand you a name tag at a single awkward meet-and-greet. The gap between the two groups is enormous, and brochures do a terrible job of telling you which is which.
So here is the current map: which lines genuinely work for solo travellers, which ships to look for, what the supplement policies really are, and how to book before the solo cabins vanish — because they always vanish first.
If you only read one table, read this one. Supplement figures come from Ship Tea’s 2026 solo cruise guide, which tracks current policies across the major lines:
| Cruise line | Dedicated solo cabins | Typical single supplement |
|---|---|---|
| Norwegian (NCL) | Yes — the largest fleet of them | 0% on solo categories |
| Virgin Voyages | Yes, every ship | 0–50% |
| Royal Caribbean | Limited, newer ships | ~100% elsewhere |
| Celebrity | Limited, Edge-series ships | ~100% elsewhere |
| Cunard | Yes, whole fleet | 50–150% on doubles |
| Holland America | Yes, newest ships | ~100% elsewhere |
| Carnival | No | 50–100% |
| Princess | Starting to add them | ~100%, discounts on select sailings |
Two patterns to absorb before we go line by line. First, a dedicated solo cabin is not a discount — it is a room priced for one person from the start, which removes the supplement question entirely. Second, those cabins are scarce: on big ships they make up roughly 2 percent of inventory and sell out about 3.5 times faster than standard balcony cabins. Whatever you choose, the booking window matters more than it does for couples.
Norwegian invented the modern solo cabin when it launched Studio staterooms on Norwegian Epic, and no one has caught up since. The line now carries around 1,000 solo staterooms across its fleet, split between the famous Studios and newer Solo Inside, Solo Oceanview, and Solo Balcony categories.
The Studios are compact — roughly 100 square feet, with a full-size bed, mood lighting, and a virtual porthole rather than a window on most ships. What makes them work is not the room but the corridor: Studios sit behind keycard access with their own private Studio Lounge, stocked with complimentary coffee and snacks all day, plus scheduled mix-and-mingle events every evening. You get a built-in community of other people travelling alone, which solves the real problem of solo cruising — not the bed, the dinner table.
Studios are on ten ships: Epic, Bliss, Breakaway, Encore, Escape, Getaway, Prima, Viva, Aqua, and Pride of America (the Hawaii-based Pride of America is the one without a lounge). NCL also staffs a solo coordinator who organises nightly meetups and group dinners — the most structured solo programming of any mainstream line.
One honest caveat from the same advisory: because Studios are priced independently, they occasionally cost more than a standard inside cabin on the identical sailing. The cabin for one is not automatically the winning price — compare before you deposit.
Virgin designed solo cabins into the fleet from day one rather than retrofitting them. Every ship carries 46 dedicated solo cabins in two flavours: the Solo Insider at about 105 square feet, and the Solo Sea View with a window. When solo cabins are sold out, supplements on standard cabins typically run 0 to 50 percent rather than the industry-standard 100 — meaningfully better maths than most competitors.
The ships are adults-only, the design is boutique-hotel rather than floating-mall, and the social scene skews younger and genuinely sociable. If NCL’s Studio Lounge is a book club, Virgin is the house party. Pick accordingly.
If your idea of a good evening at sea involves a string quartet rather than a silent disco, three names matter.
Cunard carries Britannia Single staterooms — inside and oceanview — across the whole fleet: Queen Mary 2, Queen Victoria, Queen Elizabeth, and the new Queen Anne. Book a double instead and the supplement runs 50 to 150 percent, so the singles are worth chasing. Cunard also runs organised solo gatherings and hosted dance evenings, a tradition it shares with Fred. Olsen, whose dance hosts partner solo guests at evening events.
Holland America fits solo oceanview cabins — about 127 square feet, usually with a window — on its Pinnacle-class ships such as Rotterdam, and backs them with organised solo mixers.
Two British options worth knowing: P&O put a large solo-cabin inventory, inside and balcony, on its newest ships Iona and Arvia; and Saga — over-50s only — dedicates around 20 percent of each ship to solo cabins on Spirit of Discovery and Spirit of Adventure, the highest solo ratio afloat.
Royal Caribbean and Celebrity sit awkwardly in the middle. Both have real solo cabins — Royal’s studio interiors with floor-to-ceiling “virtual balcony” screens on Quantum-class ships (Quantum, Anthem, Ovation, Odyssey, Spectrum) and a handful on Oasis-class; Celebrity’s Solo Inside and Solo Infinite Veranda rooms on Edge-series ships. But inventory is thin, solo programming is minimal, and once the solo rooms go you are back to a 100 percent supplement. Book them if the itinerary is right; just book early.
River cruising suits solo travel better than most people expect — under 200 passengers, shared excursions, communal dining where you meet everyone by day two. The supplement policies, helpfully, are often the friendliest in the industry. River Cruise Advisor’s current rundown names the standouts:
The arithmetic that makes all of the above matter: on a standard cabin with a full supplement, a 7-night Caribbean cruise listed at $800 per person costs a solo traveller $1,600 — the same room, double the bill. Mainstream 7-night fares in 2026 broadly run $600 to $1,200 per person at double occupancy, so the supplement can add more to your trip than flights and excursions combined.
Four ways to beat it, in order of reliability:
This fee logic isn’t unique to ships — tour operators play the same game, and the counter-moves overlap heavily with what I covered in how to avoid single supplement charges.
This is the question underneath the question, so let me answer it straight: on the right ship, yes, more easily than almost any other style of travel. You are in a closed environment for a week with the same faces at the pool, the trivia quiz, and the excursion bus. The structure does the work that cold-approaching strangers in a foreign city doesn’t.
The single highest-leverage move, echoed by every solo cruise guide I read: go to the solo traveller meet-and-greet on day one, even if you dread it. It is where the week’s dinner companions, excursion partners, and card-game rivals are decided. On NCL, the Studio Lounge social hour does the same job nightly. Skip these and the ship can genuinely feel lonely; attend one and it rarely does.
If what you actually want is a fully organised group experience with other women rather than a ship full of strangers, that’s a different product — I compared the options in my guide to women-only tours. And whatever you book, cruise medical situations at sea are exactly the scenario where being uninsured gets expensive fast; my breakdown of travel insurance for solo female travelers covers what the policy needs to include.
The honest summary: cruising has gone from the worst value in solo travel to one of the best engineered for it — but only on specific ships, in specific cabins, booked ahead of everyone else. Choose the line for its solo policy first and the itinerary second. The Caribbean looks the same from every balcony; the bill and the company do not.
Which cruise line is best for solo travellers?
Norwegian Cruise Line, by a comfortable margin. It carries around 1,000 solo staterooms fleetwide, charges no supplement on them, and backs the cabins with keycard-access Studio Lounges and nightly solo meetups on nine ships. Virgin Voyages is the strongest alternative for younger travellers, with 46 solo cabins on every ship.
What is a single supplement on a cruise?
A surcharge added when one person occupies a cabin priced for two — typically 50 to 100 percent of the second fare, and up to 200 percent on some river lines. Dedicated solo cabins avoid it entirely because they are priced for one occupant from the start.
Are solo cabins cheaper than regular cabins?
Usually, but not always. Solo cabins are smaller and priced for one, which beats paying a full supplement on a double. On some sailings, though, a discounted double inside cabin undercuts the solo category — always compare both before booking.
How far in advance should I book a solo cruise?
Six to twelve months for dedicated solo cabins, which represent only about 2 percent of inventory on large ships and sell out fastest. The opposite strategy also works: within 60 days of sailing, some lines discount supplements on unsold standard cabins to 25–50 percent.

Verdict: Costa Rica is one of the easiest first solo trips in Latin America. As of November 2026 the US rates it Level 2 for crime, mostly petty theft, so plan San José nights carefully, use shuttles on long hops, and keep valuables close.
Solo female travel Iceland guide: how safe it is, the real risks (weather and roads), when to go, how to get around, and when a small group tour helps.
Verdict: Iceland is one of the easiest countries in the world for a woman to travel alone. The risk is the weather and the roads, not people, so plan around conditions, share your route, and consider a day tour for anything remote.
