The tourism industry is increasingly recognizing the needs of solo travelers, as solo travel continues to grow in popularity. In April 2026, Google reported that online searches involving "solo travel" reached an all-time high this year, with queries for "women solo travel" hitting a 15-year peak. Hilton's 2026 trends report found that 26% of travelers planned to take a trip alone this year, and nearly half intended to add solo days to the front or back of a family trip. The concept of solo travel is not new, as marketing researchers identified the solo consumer as an underserved market as early as 1992. The accommodation sector typically treats double occupancy as the default unit of consumption, often imposing a "single supplement" charge on customers who travel alone. This practice reflects a pricing convention that signals the industry's historical focus on travelers with a companion. However, the costs for hotels, cruise lines, and tour operators do not necessarily decrease by half when a second person fails to materialize, which complicates the pricing model. The broader shift toward solo living is evident, with 39.7 million Americans living alone in 2025, representing 29% of all households, up from 20% in 1975. Married couples have fallen to 47% of households from 66% 50 years earlier. Living alone and vacationing alone are distinct behaviors with different causes, but they are connected by the erosion of the assumption that every adult arrives with a plus-one. In response to this trend, some travel companies have begun to adjust their offerings. Tauck, a tour operator, announced in 2026 that it is waiving the single supplement on a class of its riverboat cabins across more than 250 European river cruise departures and reducing it by up to $600 on 105 land departures. Aurora Expeditions has set aside 10 dedicated solo cabins on every sailing across its three ships, with no single supplement, through its 2026 and 2027 seasons. Norwegian Cruise Line introduced Studio staterooms in 2010, designed for one passenger, sold at single-occupancy prices, and arranged around a keycard-access Studio Lounge reserved for solo travelers. In 2024, Norwegian expanded its solo categories from nine ships to its full 19-ship fleet. However, much of this expansion involved relabeling standard double-occupancy rooms rather than retrofitting them. The Studio Lounge is reserved for guests in Solo Studios, meaning the fleetwide solo categories come with discounts but not necessarily the room full of other solo travelers. Yotel offers a room type called Solo, designed for one person, with a maximum occupancy of one, and priced at the bottom of its range. This room was built specifically for a single occupant and priced accordingly, representing a more comprehensive approach to designing for solo travelers. Despite these changes, travel advertising often still features couples, with two glasses of wine, two lounge chairs, and two silhouettes against a sunset. Solo travel, when it does appear in marketing, is often portrayed as adventurous or a journey of self-discovery. AARP's current solo-travel guide emphasizes personal growth and self-reliance. Even Norwegian's solo pitch reassures the reader that "you're pretty good company," highlighting the assumption that traveling alone is still considered exceptional. While parts of the tourism industry have made significant strides in adapting to the needs of solo travelers, treating them as an audience rather than an accommodation remains a challenge. It is about selling them what they have already said they want: control over the trip and access to other people, on their own terms. Marketing researchers identified this opportunity in 1992, and thirty-four years later, the industry is still learning to build for one. Meanwhile, the solo traveler continues to stand at reception, holding a credit card, waiting for someone to design a room.
