Cruise Lines With No Single Supplement: Every Ship With a Solo Cabin

If you cruise alone, the fare you were quoted is probably not the fare you will pay. Most lines price a cabin for two people and charge a solo traveller for both of them.

Royal Caribbean states it plainly in its own FAQ: a single guest in a standard category pays 200% of the category rate. Not a surcharge, not a fee -- twice the fare.

There are two ways around it, and they are not the same thing.

The Two Kinds of "No Single Supplement"

Structural. The line built cabins for one person. There is no supplement because there is no second passenger being priced in. Permanent, bookable any day of the year, and the reliable answer.

Promotional. The line waives or reduces the supplement on a normal double cabin for particular sailings, usually ones that are not filling. Real money, sometimes a lot of it, but temporary and capacity-controlled.

This page is the list of lines that do the first. If you want the strategy -- when to book, which promotions to watch, how to think about it -- that is in how to avoid the single supplement.

Every Ship With a Solo Cabin

Jay's Tip Count the cabins, not the ships. Royal Caribbean looks consistent at thirteen ships until you notice that Quantum-class carries twenty-eight and the older Radiance-class carries three. Three cabins on a 2,000-passenger ship sell out the day the sailing opens.

Norwegian has the deepest solo inventory at sea and it is not close. Beyond the purpose-built Studios above, Norwegian now sells solo-priced Inside, Oceanview and Balcony cabins fleetwide, and its own site states they are "always priced for one" with double occupancy rates not applying. The Studio Lounge -- the private keycard-access space that makes the Studio experience what it is -- is on nine ships, all of the above except Pride of America.

Virgin Voyages is the strongest solo product rather than the largest. Forty-six single-occupancy cabins on each of the four Lady ships, no supplement, on an adults-only ship where most people came to be sociable.

Princess is the one that surprises people. Despite the size of the fleet, solo cabins exist on Sun Princess and Star Princess only, four per ship. If you have been searching for the Princess single supplement and getting nowhere, that is why: on almost every Princess sailing there is no solo cabin to book at all.

Lines With No Solo Cabins At All

Carnival and Disney do not operate a single ship with a solo cabin. Sailing either line alone means paying the supplement or sharing. There is no third door.

Viking does not publish a standing single-supplement rate. They quote it per sailing and periodically run voyages with the supplement waived outright, so watching for those is the only strategy that works.

If You Cruise From the UK

Saga is worth knowing: around a hundred single cabins on each of Spirit of Adventure and Spirit of Discovery, with singles programming built in rather than bolted on. Fred Olsen carries real solo inventory on Balmoral and Bolette, and P&O has it across most of the fleet, led by Arvia at thirty-two and Britannia at twenty-seven.

Where the Supplement Actually Gets Waived

On the promotional side the pattern is obvious once you see it: river and expedition lines waive it far more readily than big-ship ocean lines.

Tauck waives it entirely on every Category 1 cabin on every river ship, as policy rather than promotion. American Cruise Lines has single cabins on every vessel. Riviera runs dedicated solo sailings with no supplement at all. AmaWaterways has single staterooms on several European ships and runs departures at a reduced rate rather than zero. PONANT has priced a large slice of its expedition calendar with no supplement. Windstar sits at 120% on selected itineraries, which is a reduction rather than a waiver.

The reason is capacity. A 150-passenger river boat sailing three-quarters full loses more by sailing empty than by discounting a solo. A 4,000-berth ocean ship does not have that problem.

The Third Option Nobody Lists

Every page about this topic stops at those two. There is a third.

If the entire reason you are paying double is that the second bed is empty, the direct fix is to put somebody in it. People have shared hotel rooms, ski chalets and holiday lets for decades; the challenge was never the idea, it was finding someone compatible on your specific sailing.

That is what CabinShare is for. You list the sailing you are looking at, say what you are after, and talk properly to whoever puts their hand up before anybody books anything. Some people want to split the cost and nothing else. Some want a travel companion. Both are fine, as long as you are honest about which one you are.

How This List Was Built, and Where Sources Disagree

Worth saying, because almost nobody else does.

Norwegian's Studio ship list and the fleetwide solo categories come from Norwegian's own site. Celebrity's five ships and their cabin counts come from Celebrity's own site -- which matters, because the most widely copied list on the internet has Ascent at sixteen solo cabins and Celebrity says thirty-two. The 200% figure is Royal Caribbean's own FAQ.

The remaining per-ship counts are reconciled from two independent aggregators, and they disagree in an instructive way. One lists twenty-one Norwegian ships, the other ten. Both are right: the ten are purpose-built Studios, and the other eleven are standard cabins reclassified as solo during the fleetwide expansion. Counting "solo cabins" without saying which kind is how you get two confident lists that cannot both be true.

They are also each stale in different places -- one still lists a P&O ship that left the fleet in 2019, the other omits a Cunard ship launched in 2024. So treat the counts above as accurate to within a cabin or two, verify the specific sailing before you book, and assume anything you read about solo inventory without a date on it is older than it looks.

Once you have the cabin sorted, the harder part is the week itself: solo cruising without the cringe covers meeting people once you are aboard, and how to avoid the single supplement has the booking strategy in full.
