The single supplement on most major cruise lines ranges from 50% to 100% extra above the per-person double-occupancy fare, meaning solo cruisers typically pay 150%–200% of the standard cabin price. A handful of lines offer solo cabins or waived supplements on select sailings.

Solo travelers get hit with one of cruising's most notorious fees before they even step onboard. The single supplement — the surcharge for occupying a cabin alone — can effectively double your cruise fare compared to what a couple pays per person. Here's exactly what each major line charges and how to fight back.
Single Supplement Rates by Cruise Line (2025–2026)
Most lines express the single supplement as a percentage of the double-occupancy fare. A 100% single supplement means you pay twice the per-person rate — the full cost of both berths. A 50% supplement means you pay 1.5x the per-person rate.
| Cruise Line | Typical Single Supplement | Solo Cabin Available? | Notes |
|---|---|---|---|
| Royal Caribbean | 100–200% | No | Waived promos run occasionally; Studio cabins rumored but not standard |
| Carnival Cruise Line | 100–200% | No | Supplement varies by itinerary and category; some sailings offer 50% deals |
| Norwegian Cruise Line | 0% (Studio cabins) | Yes — 128 Studios | Studio cabins priced for solo occupancy; no supplement |
| Celebrity Cruises | 100–200% | No | Solo promos pop up on off-peak sailings; Edge class has no dedicated solo rooms |
| MSC Cruises | 100–200% | No | Yacht Club suites can hit 200%; inside cabins sometimes 50% on slower sailings |
| Princess Cruises | 100–200% | No | Occasional solo saver fares; guarantee cabins sometimes waive supplement |
| Holland America | 100–200% | No | Strong solo discounts on repositioning sailings; some at 50% |
| Disney Cruise Line | 100–200% | No | Rarely discounts; premium brand, premium pain for solos |
| Virgin Voyages | 100% baseline | No | All-inclusive pricing softens the blow; no kids = no families doubling up |
| Cunard | 100–200% | No | Queen Anne launched with some solo cabins; check current fleet assignments |
| Saga Cruises | 0–50% | Yes — dedicated solo cabins | UK-focused line; genuinely solo-friendly pricing |

What Drives the Single Supplement Cost
Cabin category matters enormously. The supplement percentage often stays flat, but the base fare it's applied to climbs fast. A 100% supplement on a $500/person inside cabin costs you an extra $500. On a $2,500/person balcony, that same 100% supplement is now $2,500. Solos in suites can get absolutely torched.
Itinerary and demand. Shoulder-season sailings and repositioning cruises have lower load factors — cruise lines are more motivated to fill empty beds and will drop solo supplements to 50% or waive them entirely. Peak Caribbean and Mediterranean summer sailings? Expect full 200% supplements with zero apology.
Booking timing. Last-minute inventory (14–60 days out) sometimes unlocks solo deals as lines scramble to fill cabins. Early booking occasionally locks in a promotional rate that includes reduced supplements.
Loyalty status. Some lines offer supplement reductions as a loyalty perk. Norwegian's Latitudes program and Princess's Captain's Circle have offered solo supplement discounts on select sailings.
Cruise line philosophy. Norwegian made a deliberate business decision to build Studio cabins specifically for solos on their newer ships. That's the exception, not the rule — most lines simply don't care enough about the solo market to invest in the cabin infrastructure.

Real Dollar Impact: What Solos Actually Pay
Here's how the single supplement plays out in practice across budget tiers for a 7-night Caribbean cruise (2025 pricing):
| Tier | Per-Person Fare (Double) | Solo w/ 100% Supplement | Solo w/ 50% Supplement | NCL Studio Cabin |
|---|---|---|---|---|
| Budget (Inside) | $500 | $1,000 | $750 | $650–$800 |
| Mid-Range (Balcony) | $1,200 | $2,400 | $1,800 | N/A (no Studio balconies) |
| Splurge (Suite) | $3,500 | $7,000 | $5,250 | N/A |
That balcony column hurts to look at. $2,400 for one person in a balcony cabin while couples pay $1,200 each. It's genuinely punitive.
Practical Tips to Cut the Single Supplement
1. Book Norwegian's Studio cabins. This is the single best structural solution available. Studios are small (about 100 sq ft) but have their own lounge — the Studio Lounge — where you meet other solos. Zero supplement. Available on Norwegian Escape, Breakaway, Bliss, Joy, Encore, Prima, and Viva.
2. Hunt repositioning cruises. Transatlantic and transpacific repositioning sailings routinely drop supplements to 50% or waive them. You get longer itineraries, port-heavy days, and no supplement torture. Holland America and Cunard are especially good here.
3. Use a solo cruise specialist. Agencies like SinglesCruise.com or Solo Cruises charter group space and split cabin costs — you're matched with a same-gender roommate and each pay the standard per-person rate. Not for everyone, but it genuinely solves the math problem.
4. Wait for last-minute solo deals. Sign up for email alerts from the cruise line and check 30–45 days before sailing. Unsold inventory sometimes appears at dramatically reduced solo rates. High risk, high reward.
5. Consider cruise lines with genuine solo commitment. Saga Cruises (UK-based, adults 50+) builds solo cabins into their ships and charges 0–50% supplements as standard policy. If the demographic fits, it's worth considering.
6. Guarantee cabins sometimes help. On some lines, booking a guarantee (GTY) inside cabin assigns you to any available inside room. Occasionally these go to single travelers at reduced supplement as a fill-the-ship measure.
7. Negotiate directly or through a travel agent. In slow booking periods, a skilled travel agent can sometimes extract a reduced single supplement, especially for groups of solo travelers booking multiple cabins on the same sailing.
Best Cruise Lines for Solo Travelers (Ranked)
| Rank | Line | Why | Best For |
|---|---|---|---|
| 1 | Norwegian Cruise Line | Studio cabins = zero supplement | Solo travelers who want solo-specific infrastructure |
| 2 | Holland America | Frequent 50% supplement promos, great repositioning deals | Mature solos, value-conscious travelers |
| 3 | Virgin Voyages | 100% supplement but all-inclusive pricing softens it | Solo travelers who drink and like a premium vibe |
| 4 | Princess | Regular solo fare sales, decent loyalty perks | Loyal Princess cruisers going solo |
| 5 | MSC | Inside cabins sometimes at 50% supplement | Budget-focused solos willing to book strategically |
Disney and Celebrity land at the bottom for solos — premium pricing combined with full supplements and no structural solo solution makes them genuinely poor value for single travelers.
The single supplement is one of cruising's most solvable problems if you know where to look. Norwegian's Studio cabins are the cleanest answer. Repositioning sailings are the next best move. And anything else requires you to hunt deals aggressively rather than booking at face value.
