I’ve only sailed solo once myself, a short Caribbean trip on a Celebrity Edge class ship. So this isn’t a ranking built purely on firsthand comparison, it’s my honest read on where each major line actually stands for solo travelers, based on that one real trip plus a lot of digging into what the rest of the fleet offers. I’ll be upfront about which is which as I go.
1. Norwegian, the clear leader
I haven’t sailed Norwegian solo, but the numbers make it hard to argue with. Norwegian was the first mainstream line to build dedicated solo staterooms back in 2010, and they’ve kept expanding ever since, now offering nearly 1,000 solo cabins across their 19-ship fleet in Inside, Oceanview, and Balcony categories, plus the original Studio design. Solo cabins on Studio ships come with access to a private Studio Lounge, a space reserved only for solo guests to gather, which nobody else in the industry matches. If meeting other solo travelers matters to you as much as the cabin itself, Norwegian is the one to book.
2. Celebrity, the one I actually know
This is the line I’ve sailed. My cabin was the Edge Single Stateroom with Infinite Veranda, and it’s genuinely one of the best solo products at sea if a real balcony matters more to you than a lounge full of strangers. Each Edge class ship carries sixteen of these cabins, roughly 130 to 175 square feet plus the veranda, laid out for one person from the start rather than a shrunk-down double. I skipped the main dining room on my trip, not because of any solo awkwardness, but because on a short cruise I’d rather grab a quick dinner on my own schedule than commit to the full multi-course pace each night, even with Edge class giving you four different main dining rooms like Cosmopolitan and Tuscan to rotate through. That trade felt easy solo in a way it wouldn’t with a group. One thing worth knowing before you book, closet space in these cabins is tight, and if you tend to overpack the way I do, plan on living out of a suitcase more than you’d like. The veranda made up for it. Only sixteen per ship means they sell out early, book ahead if this is the line you want.
3. Virgin Voyages, best atmosphere for meeting people
I haven’t sailed Virgin, but their adults-only policy changes the whole equation for solo travelers in a way no other line on this list can replicate. No kids, no family-dinner energy, a crowd that skews toward people traveling independently on purpose. They offer two dedicated solo cabin types, Solo Insider and Solo Sea View, both priced for one with no supplement. Solo Insiders run around 40 per ship, Solo Sea View cabins are more limited, and both categories sell out fast, especially on Caribbean and Mediterranean sailings. If the social side of solo cruising matters more than the room itself, this is worth strong consideration.
4. Royal Caribbean, solid but limited
Royal Caribbean has solo studio cabins on select Quantum and Oasis class ships, mostly interior with a small number of balcony options. Outside those cabins, their standard single supplement runs 200 percent, reduced to 150 percent once you’ve built up enough Crown & Anchor loyalty points. If you’re already tied into their loyalty program from cruising with family or a group, that reduction makes solo trips on Royal Caribbean more reasonable. If you’re starting from zero loyalty status, the math favors a line with a true solo-priced cabin instead.
5. Holland America, small but real
Holland America’s three Pinnacle class ships each carry about twelve solo cabins, all with ocean views, which is a nice touch since most solo cabins across the industry skip windows entirely. It’s a small program, but a genuine one, not just a discount on a double.
6. Cunard, traditional and a little formal
Cunard offers dedicated single Inside and Oceanview cabins on three of its four ships, Queen Mary 2, Queen Victoria, and Queen Elizabeth. Their newest ship, Queen Anne, launched in 2024 without a solo cabin category, breaking from the rest of the fleet. The onboard culture skews more formal and traditional than most modern lines, which tends to appeal to a specific kind of solo traveler, often older, often looking for a more structured, elegant atmosphere rather than a party scene.
7. MSC and Princess, newer to the game
Both lines have added dedicated solo cabins only recently, MSC on select newer ships and Princess starting with Sun Princess. Worth watching as these programs expand, but neither has the track record or cabin count that Norwegian, Celebrity, or Virgin Voyages already have.
8. Carnival and Oceania, skip for a dedicated solo trip
Carnival has no dedicated solo cabin category and charges the full 200 percent supplement with no way around it. It’s still the cheapest entry point in raw dollars if budget is genuinely the only factor, but you’re not getting any solo-specific product for that price. Oceania doesn’t confirm dedicated solo pricing as a standard fleet-wide offering either, worth checking directly if their smaller luxury ship experience appeals to you more than the solo cabin question.
Where I’d point a first-timer
If I were booking my next solo trip today, based on what I’ve sailed and what I’ve researched, I’d put Norwegian and Celebrity at the top of the list, then Virgin Voyages if the social atmosphere matters as much as the room. I want to do a full Celebrity solo trip again, dining room included this time, and I’ll update this ranking with more firsthand experience once I have it.
