Most cruise pricing assumes two people per cabin, and a solo traveler booking a standard room typically gets hit with a single supplement — often the full second-passenger fare, effectively doubling the cost. A handful of lines have built real solo-friendly options instead: dedicated single-occupancy cabins, no single supplement, and lounges built specifically for meeting other solo travelers. Knowing which lines actually did this work, versus which just charge you double, changes the math on solo cruising completely.
How the major lines compare for solo travelers
| Cruise line | Solo cabin option | Single supplement | Solo-specific features |
|---|---|---|---|
| Norwegian Cruise Line | Dedicated Studio cabins on 10 ships, ~100 sq ft, full-size bed, private bath | None — no single supplement since 2010 | Private Studio Lounge with nightly hosted meetups, free espresso and snacks |
| Royal Caribbean | Studio cabins on Quantum-class ships and select Oasis-class ships | None on Studio cabins; ~100% on the rest of the fleet | Limited outside of Studio cabins — book early since availability is tight |
| Virgin Voyages | Solo-friendly cabin categories fleet-wide | Reduced compared to mainstream lines | Every ship is adults-only (18+); crowd skews independent travelers in their 30s-60s |
| Holland America | Single-occupancy staterooms on select ships | Reduced on designated solo cabins | Solo-friendly reputation, especially on longer itineraries |
What a single supplement actually costs you
On lines without dedicated solo cabins, booking a standard double-occupancy room alone typically triggers a single supplement of around 100% of the second passenger's fare — in practice, you pay close to what two people would pay for one person's trip. Studio and single-occupancy cabins sidestep this entirely by pricing the room for one person from the start, which is why they're worth planning around even if the cabin itself is smaller.
Comparing the true per-person cost — Studio/solo cabin fare on a solo-friendly line versus a standard cabin plus single supplement elsewhere — usually settles the decision fast. [Replace this box with your actual cruise booking affiliate link once approved.]
Example: Compare solo cruise fares →How to meet people on a solo cruise
| Approach | Why it works |
|---|---|
| Attend the first-day solo meetup | Most lines organize a casual solo travelers' gathering, usually day one, in a ship lounge or bar |
| Use the Studio Lounge (Norwegian) or equivalent solo space | A dedicated space built for solo travelers to gather, rather than an ad-hoc meeting spot |
| Request shared dining seating | Ask to be seated with other solo travelers or at a shared table instead of dining alone |
| Join pre-cruise Facebook groups | Most sailings have an unofficial group where guests coordinate meetups before boarding |
| Pick a regular bar and bartender | Becoming a familiar face at one bar creates an easy, low-pressure way to have recurring conversations |
Other lines worth checking for solo deals
Several river cruise lines have leaned into solo-friendly pricing for 2026 — Tauck is waiving the single supplement on Category 1 cabins across more than 250 departures, and AmaWaterways and Riviera River Cruises have run similar reduced or waived supplement offers on select sailings. These promotions rotate seasonally, so it's worth checking current offers directly with the line if a river cruise is on your list alongside ocean options.
The bottom line
Norwegian remains the standout for solo cruisers in 2026 — the only mainstream line combining a genuine no-supplement Studio fare with a real solo lounge and nightly hosted meetups. Royal Caribbean and Virgin Voyages are strong alternatives if Norwegian's itineraries don't fit, but outside of dedicated solo cabin categories, expect most lines to charge close to double for a solo traveler in a standard room — checking cabin type before comparing prices across lines is the single biggest lever for keeping solo cruise costs reasonable.
