What Is a Single Supplement & How Can You Avoid It?

Traveling Solo? Let's Talk About the Single Supplement

Solo travel continues to grow, and I hear from more and more travelers who are ready to stop waiting for someone else to be available before taking the trip they want.

I love that.

Unfortunately, there's one part of traveling solo that can come as a pretty unpleasant surprise: the single supplement.

What Is a Single Supplement on a Cruise?

"A cruise single supplement is an additional charge a solo traveler may pay when occupying a cabin designed and priced for two guests."

Most cruise fares are advertised per person, based on double occupancy. That means the cruise line is expecting two people to occupy the cabin. For example, if a cruise is advertised at $3,000 per person, the cruise line is expecting to receive approximately $6,000 for that cabin. If one person wants the same cabin, the cruise line may charge a single supplement to make up for some or all of that lost second fare.

Why Do Solo Cruisers Pay More?

Depending on the cruise line, itinerary, cabin category, and sailing date, that supplement can be significant. In some cases, a solo traveler can end up paying close to what two people would have paid for the cabin.

And yes... I know how frustrating that sounds.

However, not every cruise line handles solo pricing the same way. Some have dedicated solo cabins designed and priced specifically for one person, while others regularly offer reduced single supplements or promotions where the extra fee is waived completely. Choosing the right cruise line and the right sailing makes all the difference.

Best Cruise Lines for Solo Travelers

Crystal

Crystal is one of my favorite options to look at for luxury solo travelers. In addition to offering dedicated Solo Guest Rooms, Crystal regularly features select voyages with reduced solo supplements. This gives solo travelers an opportunity to experience a true luxury cruise without necessarily paying double the advertised fare.

Crystal is also particularly appealing because of the onboard atmosphere. There are plenty of opportunities to socialize, dine with others, and meet fellow travelers, but you can also easily enjoy your own space whenever you want it.

Which Cruise Lines Offer Reduced Single Supplements?

Many top-tier cruise lines are recognizing the boom in solo travel and adapting their inventory. Beyond dedicated solo rooms, lines frequently run capacity-controlled promotions that waive or heavily discount the single supplement on specific itineraries—especially during shoulder seasons or repositioning cruises.

Are River Cruises Good for Solo Travelers?

River cruising is an exceptional option for solo travelers, and several European river cruise lines stand out for their solo-friendly policies:

• AmaWaterways: This line periodically offers reduced or completely waived single supplements on select sailings and cabin categories. Some of its European ships also feature a limited number of staterooms specifically designed for single occupancy. River cruising naturally works well for solo travelers because excursions are organized in groups, and the intimate size of the ships makes it much easier to meet fellow passengers.
• Tauck: Another company worth considering for high-end European river cruises. Tauck waives the single supplement on Category 1 cabins on its European river cruises, meaning a solo traveler pays the exact same per-person fare as someone sharing the cabin. These cabins are limited, so booking early is essential. Tauck also offers solo savings on select other categories and departures.

How to Find Cruises With Low or No Single Supplements

Look Beyond the Percentage

Here's where travelers sometimes get caught up in the numbers: a cruise advertising a "0% single supplement" isn't automatically the best value. You still need to evaluate:

• The actual total price
• What is included in the fare (dining, beverages, Wi-Fi, gratuities)
• Cabin size and location
• Itinerary and shore excursions
• The overall onboard experience

A $4,000 cruise with no single supplement isn't necessarily a better deal than a $3,000 cruise with a 25% supplement. The final price and overall experience matter more than the percentage advertised.

Timing Can Make a Huge Difference

Solo pricing is often capacity-controlled. A cruise line might offer a fantastic solo rate on one departure and a much higher supplement on the exact same itinerary two weeks later. That's why flexibility can save you hundreds—or even thousands—of dollars.

Traveling Solo Doesn't Mean Traveling Alone

This is the biggest misconception I hear. Cruises and guided tours are some of the easiest ways to travel solo because you're surrounded by people who share your love for travel. Excursions naturally bring people together, and meals, lounges, and onboard activities provide organic opportunities to socialize. You can spend the afternoon exploring with a group and have dinner by yourself whenever you choose.

My Advice for Solo Travelers

Don't automatically assume a cruise or tour is too expensive just because you're traveling alone. The key is knowing where to look, staying flexible with your dates, and keeping an eye out for changing promotions.

You shouldn't have to wait for someone else to be ready before you start seeing the world.
