Single supplements on cruises remain one of the most persistent financial penalties facing solo travellers over 60. This guide names specific cruise lines — the fair ones and the ones still charging near-double — and gives you the practical language to push back, ask better questions, and find the itineraries where travelling alone does not cost you a fortune.
What Is a Single Supplement and Why Does It Exist?
A single supplement is the extra charge a cruise line applies when one person occupies a cabin built and priced for two. Because cruise lines base their revenue model on two fare-paying passengers per cabin, a solo traveller is expected to cover the shortfall. In practice, that means paying anywhere from 50% to 100% on top of the per-person twin-share fare — sometimes more on premium lines during peak season.
For a traveller in regional Victoria comparing cruise options, the maths can be brutal. Take an indicative 10-night Mediterranean sailing priced at around AUD 3,500 per person in a twin-share interior cabin. At a 100% single supplement, the solo fare becomes roughly AUD 7,000 — the same price as two people travelling together. At 50%, it sits around AUD 5,250. That gap of AUD 1,750 is real money, and on a longer voyage or a premium-category cabin, the difference compounds quickly.
The supplement is not a conspiracy; it reflects a genuine revenue model. But the way it is disclosed — or quietly buried in fare breakdowns — is where the industry earns its criticism. Many booking sites still display per-person twin-share pricing without flagging the supplement until checkout, which wastes time and raises false expectations for solo travellers doing their research.
Which Cruise Lines Have Dedicated Solo Cabins?
Norwegian Cruise Line is the most established example of a line that has genuinely invested in solo infrastructure. Its Studio cabins — available on ships including Norwegian Epic, Breakaway, Getaway, Escape, and Joy — are purpose-built single-occupancy rooms with their own private lounge area called the Studio Lounge. The rooms are compact but functional, typically around 7–9 square metres, and they carry no single supplement because they are priced as solo cabins from the outset. Indicatively, a 7-night Caribbean or European sailing in a Studio has been running at roughly AUD 1,800–2,800 depending on season and itinerary — confirm current fares directly with NCL or a licensed travel agent.
Cunard introduced dedicated solo staterooms on its newest ship, Queen Anne, which entered service in 2024. These cabins are designed for single occupancy with no supplement, and the line has positioned them as a genuine alternative rather than an afterthought. Cunard's brand sits at the premium end, so indicative solo fares for transatlantic or European voyages start from around AUD 3,200–5,500 for 7–14 nights. Given the line's reputation for structured programming and a well-travelled older demographic, it suits the traveller who wants company at dinner without having to share a cabin.
P&O Cruises Australia — relevant for those who prefer to sail from Australian home ports like Melbourne, Sydney, or Brisbane — has at times offered solo guarantee fares and solo-friendly pricing promotions, though it does not maintain a permanent dedicated solo cabin category across its fleet. This means availability and supplement rates vary considerably by sailing and by how far in advance you book. It is worth asking specifically about solo guarantee cabins, where you pay a set solo rate and are assigned a cabin from a pool — you may get an upgrade, but you have less control over location.
Which Lines Still Charge Near-Double — and Should Be Named
Celebrity Cruises, part of Royal Caribbean Group, applies a standard 100% single supplement on most cabin categories across most itineraries. There are occasional promotional exceptions — typically flash sales or specific departures where solo supplements are reduced to 50% or waived — but these are not a structural feature of the product. If you are quoted a per-person fare on a Celebrity sailing and you are travelling alone, assume you are paying double unless you have written confirmation otherwise.
Royal Caribbean International operates similarly. Its ships are large, programming is abundant, and the experience is well-regarded, but the default single supplement is 100% on standard cabins. The line does not have a dedicated solo cabin product comparable to NCL's Studios. Solo travellers boarding Royal Caribbean are effectively subsidising the cabin revenue model for couples, with no structural acknowledgement that single occupancy is a legitimate and growing market segment.
MSC Cruises, which has been actively growing its Australian market presence, also defaults to 100% supplements in most configurations. Holland America Line — popular with older Australian travellers for its longer, port-intensive itineraries — similarly lacks a dedicated solo cabin programme, though it does periodically offer reduced supplement promotions, particularly on its longer World Voyage segments. The honest assessment: these lines are not hostile to solo travellers, but they have not chosen to invest in infrastructure that treats solo travel as a first-class option. You are welcome aboard, but you will pay for the privilege of your own space.
Lines That Sit in the Middle: Reduced Supplements Rather Than Zero
Viking Ocean Cruises occupies a distinct position. It does not have purpose-built solo cabins, but it has made a practice of offering 50% supplements on select itineraries and sailings — particularly on longer voyages and during shoulder-season departures. For a line that attracts a well-travelled, older demographic and is known for its inclusive pricing model (most shore excursions, beverages, and gratuities included), a 50% supplement is meaningfully different from 100%. Indicatively, solo fares on an 8-night Scandinavian or Mediterranean Viking sailing have been running at roughly AUD 5,500–9,000 depending on season; confirm current pricing directly with Viking Australia.
Scenic Luxury Cruises and Tours, an Australian-founded premium operator, has run solo supplement reductions on both its river and ocean products. River cruising in particular — on the Rhine, Danube, or Douro — can be a practical choice for solo travellers over 60 because the ships are small (typically 130–190 passengers), itineraries are port-intensive, and the environment is naturally more social than a large ocean vessel. Scenic's supplement policies vary by departure, so ask your travel agent to request the current solo supplement schedule in writing before you commit.
Silversea Cruises, at the ultra-luxury end, has historically offered solo savings on specific voyages, sometimes waiving the supplement entirely on longer expedition itineraries. The base fares are high — indicative solo fares for an ultra-luxury sailing can sit from AUD 8,000–15,000 and well above for longer expeditions — but the all-inclusive model means fewer add-on costs. For a traveller who wants genuine luxury and is prepared to spend accordingly, Silversea's occasional solo promotions are worth monitoring.
How Quickly Do Solo Cabins Sell Out — and What That Means for Planning
On Norwegian Cruise Line, Studio cabins on popular itineraries — particularly Mediterranean summer sailings and Caribbean departures over the Australian holiday period — can sell out six to twelve months in advance. This is not marketing language; it reflects the reality that there is a large and growing pool of solo travellers competing for a genuinely limited inventory. If you have a specific itinerary or departure date in mind, the practical advice is to begin enquiring at least nine to twelve months out and to ask your travel agent to monitor waitlist availability.
Cunard's Queen Anne solo staterooms are newer to the market, and availability patterns are still establishing themselves, but the early indication from the 2024-25 season is that they sell briskly on transatlantic crossings and European summer sailings. If you are planning a 2026 departure, the first quarter of 2025 is a reasonable window to begin serious enquiry. Waiting until six months out risks finding the solo inventory exhausted while twin-share cabins remain plentiful — a frustrating position that reinforces the sense that solo travellers are an afterthought.
For lines without dedicated solo cabins — where you are booking a standard cabin at a solo rate — the timing calculus is different. Your negotiating position is stronger during the line's promotional windows, typically in January-February and again in August-September when lines push sales to fill forward inventory. These are the moments when supplement reductions or waivers are most likely to appear. A good travel agent who specialises in cruising will know these cycles and can advise you without you having to monitor multiple websites.
Questions to Ask a Travel Agent Directly — and Why It Matters
The language you use with a travel agent shapes what you are offered. Vague enquiries get vague responses. Specific questions get specific answers — and sometimes better deals. Before you commit to anything, ask: 'What is the single supplement percentage on this specific sailing, in writing?' Then ask: 'Does this line have any solo cabin categories with no supplement, and are any available on this itinerary?' Then ask: 'What is the cancellation policy for a solo booking, and does travel insurance cover supplement costs if I need to cancel?' These are not difficult questions, but many solo travellers never ask them and later feel blindsided.
Ask your agent whether they have access to group space on the sailing. Some travel agencies purchase blocks of cabins at discounted rates and can pass a portion of that saving to solo travellers, effectively reducing your supplement. This is more common than most people realise, and it is worth asking directly: 'Do you hold any group space on this departure?' Also ask whether the line operates a 'solo guarantee' programme — where you pay a fixed solo rate and accept the cabin assignment — versus a specific cabin booking. Guarantee programmes can offer genuine savings but require flexibility.
Finally, ask about the line's onboard social programming for solo travellers. Some ships — particularly NCL with its Studio Lounge, and Cunard with its structured dining and enrichment programme — have genuine infrastructure for meeting other travellers. Others have nothing. As a solo traveller, knowing whether there is a designated space or organised activity for people travelling alone can make a meaningful difference to the experience, particularly on a longer sailing.
The Broader Advocacy Point: This Is a Fairness Issue
The solo supplement disproportionately affects women. Australian Bureau of Statistics data consistently shows that women outlive men, and that women over 60 are more likely to be widowed, divorced, or simply choosing to travel independently. The cruise industry's default response — charge double or near-double — effectively prices out a large segment of travellers who have the time, the inclination, and in many cases the savings to travel, but who refuse to absorb an arbitrary financial penalty for their relationship status. Framing this as a 'revenue model necessity' does not change what it is in practice.
Several cruise lines have recognised this and responded structurally — NCL and Cunard most visibly. Others have responded with occasional promotions that create the impression of fairness without changing the underlying policy. The test of genuine commitment is whether solo cabin inventory grows over time and whether supplement reductions are structural rather than promotional. Travellers and advocates should hold lines accountable by asking publicly, by choosing lines that have acted, and by directing their spending accordingly.
For travellers based in regional Victoria or elsewhere in Australia, the tyranny of distance adds another layer. Long-haul flights to reach embarkation ports in Europe or North America represent a significant upfront cost before the cruise fare is even considered. Paying a 100% supplement on top of that is a compounding burden. It is entirely reasonable to make cruise line supplement policy a deciding factor in your itinerary choice — and to tell your travel agent that is what you are doing. The industry listens to purchasing behaviour more reliably than it listens to complaints.
Key takeaways
- Norwegian Cruise Line's Studio cabins and Cunard's Queen Anne solo staterooms are the clearest examples of cruise lines that have structurally eliminated the single supplement for solo travellers.
- Celebrity Cruises and Royal Caribbean International both default to a 100% single supplement on most cabins, meaning solo travellers pay roughly double the per-person twin-share fare.
- Viking Ocean Cruises regularly offers a 50% supplement on select itineraries, making it a meaningfully fairer option than lines that charge full double without a dedicated solo product.
- Solo cabins on popular Norwegian Cruise Line sailings can sell out six to twelve months in advance, making early enquiry essential rather than optional.
- Asking a travel agent for the single supplement percentage in writing, on a specific sailing, is the single most useful step a solo traveller can take before committing to any cruise booking.
- The solo supplement disproportionately affects older women, and choosing cruise lines that have acted structurally — not just occasionally — is a legitimate form of consumer advocacy.

Frequently asked questions
Which cruise lines have no single supplement for solo travellers?
Norwegian Cruise Line offers Studio cabins — purpose-built single-occupancy rooms priced without a supplement — on several ships including Norwegian Epic, Escape, and Breakaway. Cunard has introduced dedicated solo staterooms on Queen Anne with no supplement. These are the two most established examples of lines that have structurally eliminated the charge rather than reducing it occasionally through promotions.
What is a typical single supplement percentage on Australian cruises?
The industry standard default is 100%, meaning a solo traveller pays double the per-person twin-share fare. Some lines — including Viking Ocean Cruises on select itineraries — offer 50% supplements. A small number of departures on various lines waive the supplement entirely through promotions. Always ask for the supplement percentage in writing for your specific sailing, as it varies by line, ship, cabin category, and departure date.
How far in advance should a solo traveller book a cruise to get a solo cabin?
For dedicated solo cabins on Norwegian Cruise Line, particularly on Mediterranean summer or Caribbean sailings, booking nine to twelve months in advance is advisable. Cunard's Queen Anne solo staterooms on transatlantic and European itineraries are also selling well. Waiting until six months before departure risks finding solo inventory exhausted while twin-share cabins remain available.
Can a travel agent reduce or waive a single supplement?
Sometimes, yes. Travel agents who hold group space on a sailing may be able to pass a portion of their group discount to solo travellers, effectively reducing the supplement. It is worth asking directly whether the agent holds group space on your preferred departure. Agents can also advise on solo guarantee programmes, where you pay a fixed solo rate and accept the cabin assignment, which can reduce costs but limits your control over cabin location.
Is river cruising a better option than ocean cruising for solo travellers over 60?
River cruising can be a practical choice for solo travellers over 60. Ships are small — typically 130 to 190 passengers — itineraries are port-intensive, and the environment is naturally more social. Operators including Scenic and Avalon Waterways have offered reduced solo supplements on select European river departures. Mobility access varies by ship and itinerary, so ask specifically about gangway arrangements and whether shore excursions involve significant walking or uneven terrain.
