Cruise cabins are priced for two people, and sailing solo usually means paying a "single supplement" that can effectively double the fare. The good news is that this isn't universal anymore — a handful of lines have built dedicated solo cabins with no supplement at all, and others offer roommate matching or promotional waivers that cut the extra cost significantly.
Why the supplement exists
A standard cruise cabin is priced assuming double occupancy — the base fare reflects two people splitting the cost of the space. Booking that same cabin alone means the cruise line isn't collecting the second passenger's fare, and the single supplement (commonly 100% of the per-person rate, sometimes as high as 125-200%) is how lines recover that gap.
Lines with dedicated solo cabins (no supplement)
| Cruise line | Solo cabin option | Notes |
|---|---|---|
| Norwegian Cruise Line | Studio cabins, no single supplement since 2010 | Available on 10 ships including Aqua, Bliss, Encore, Epic, Prima, Viva; includes a private Studio Lounge with nightly meetups |
| Virgin Voyages | Solo Insider (105 sq ft) and Solo Sea View (130 sq ft) | No supplement, but limited inventory — about 46 solo cabins per ship out of 2,700+ total passengers |
| MSC, Royal Caribbean (Quantum-class), P&O, Saga | Purpose-built solo cabins on select ships | Availability varies by ship — check the specific vessel, not just the line |
Roommate matching as an alternative
For travelers open to sharing a cabin, several lines offer same-gender roommate matching that waives the supplement entirely if a match is found. Princess Cruises' Solo Traveler Guarantee waives the supplement on a booked balcony cabin if the line can't find a same-gender roommate — effectively a win either way. Holland America runs a similar Single Share program pairing solo travelers with same-gender roommates.
Comparing the total cost of a dedicated solo cabin against a standard cabin with the single supplement applied is worth doing on every line — the "cheaper per square foot" solo cabin isn't always the lower total cost once the math is run.

River cruise lines generally charge a much lower single supplement than ocean cruises — typically 20-25% rather than the 100% standard on mainstream ocean lines. On the ocean side, watch for promotional sailings: Princess, Holland America, MSC, and Virgin Voyages periodically run limited-time sales reducing the supplement to 25-50% of the standard rate rather than waiving it, worth watching for on flexible travel dates.
| Strategy | Typical result |
|---|---|
| Book a purpose-built solo cabin (Norwegian, Virgin Voyages) | 0% supplement, but limited inventory |
| Use roommate matching (Princess, Holland America) | Supplement waived if a match is found |
| Choose a river cruise instead of ocean | 20-25% supplement instead of 100% |
| Watch for promotional sailings | 25-50% supplement instead of full price, select dates only |
Repositioning cruises and shoulder-season sailings are more likely to carry reduced or waived single supplements since cruise lines are more motivated to fill cabins — flexible solo travelers can often find meaningfully better rates by watching these windows.

The standard single supplement — often a full 100% of the per-person fare — is real, but it's no longer unavoidable. Norwegian and Virgin Voyages both offer purpose-built solo cabins with zero supplement, Princess and Holland America offer roommate matching that can waive it, and river cruises carry a meaningfully lower supplement than ocean cruises by default. Comparing all of these against the plain double-occupancy-plus-supplement price before booking is the only way to know which option actually costs less.
