Solo travel is on the rise, with online searches for "solo travel" reaching an all-time high in 2026, according to Google data. Searches for "women solo travel" also hit a 15-year peak, indicating growing interest, particularly among women. A 2026 report by Hilton found that 26% of travelers planned to embark on a solo trip that year, and nearly half intended to include solo days at the start or end of a family vacation. This trend reflects a broader shift in how people approach travel, with more individuals choosing to explore independently. The concept of solo travel is not new, but the travel industry has historically been structured around group travel, often assuming that people travel with a partner or companion. This is evident in the way accommodations are priced, with double occupancy as the standard. Solo travelers often face a "single supplement" — an extra fee to cover the cost of a room for one person — which can make solo travel more expensive. This pricing model reflects the industry's traditional assumption that most travelers come in pairs. In response to the growing demand, some travel companies have begun adjusting their offerings to better accommodate solo travelers. For example, Tauck, a travel company specializing in guided tours, announced in 2026 that it would eliminate the single supplement for a specific class of riverboat cabins on over 250 European river cruise departures. Aurora Expeditions, which offers adventure-focused cruises, has also made changes, reserving 10 solo cabins on each of its three ships without any additional charges for the 2026 and 2027 seasons. Demographic changes are one reason for the rise in solo travel. In 2025, 39.7 million Americans lived alone, accounting for 29% of all households — up from 20% in 1975. At the same time, the number of married couples as a percentage of households has dropped from 66% in 1975 to 47% in 2025. While living alone has become more common, it is not always the same as traveling alone, as the motivations and experiences can differ. Despite these changes, the travel industry is still learning how to best meet the needs of solo travelers, with a focus on offering more control and flexibility in trip planning.
