Understanding the Single Supplement in Travel: What Solo Travelers Need to Know

If you’ve ever booked a hotel, cruise, or guided tour as a solo traveler, you’ve probably seen the term single supplement. This added fee can be confusing and frustrating, especially for those traveling alone. In this guide, we’ll explain what a single supplement is, why it exists, and how savvy travelers can reduce or avoid it.

What Is a Single Supplement?

A single supplement is an extra charge added when only one person occupies a room designed for two people. Most hotels and cruise cabins are priced for double occupancy. For example, if a room costs $200 per night for two guests, two people would pay $100 each. If just one person stays in that room, they pay the full $200, and the extra amount is considered the single supplement.

Why Does the Single Supplement Exist?

Hotels and cruise lines design most rooms for double occupancy to maximize revenue. When a room is occupied by one guest instead of two, the business earns less from:

  • Room revenue

  • Dining and bar sales

  • Excursions and onboard shopping (especially on cruises)

On cruise ships, the impact is even greater. A ship built for 2,000 passengers carries only 1,000 if every cabin is used by one person, which significantly reduces onboard spending. The single supplement helps offset these losses.

Do Any Travel Companies Reduce the Single Supplement?

Yes — but it’s uncommon. Some tour operators work hard to make solo travel more affordable. The Traveling Professor actively negotiates reduced single supplements for many of its small group tours. While you may occasionally see “no single supplement” offers, they are rare and usually limited in availability.

Why Don’t Hotels Offer More Single Rooms?

A small number of hotels offer dedicated single rooms, but these are limited. Most hotel properties are designed and built around double occupancy, so creating and maintaining single rooms is not always practical or profitable.

Does the Single Supplement Apply to Everything?

In most cases, the single supplement applies only to hotel rooms or cruise cabins. Flights, guided excursions, transfers, and entrance fees are typically priced per person and are not affected by single occupancy.

How to Avoid or Reduce the Single Supplement

Solo travelers can use several proven strategies to lower or avoid this extra cost:

  • Stay in hostels or dorm-style accommodations, which are priced per person

  • Book tours that offer reduced single supplements, like those from The Traveling Professor

  • Share a room with another solo traveler, which many tour companies can help arrange

Travel Smarter as a Solo Traveler

At The Traveling Professor, solo travelers are always welcome. Their small group tours through Europe, South America, and Canada are thoughtfully designed to be comfortable, social, and affordable. The company works hard to minimize single supplements whenever possible, helping solo travelers explore the world without unnecessary extra costs.
