"Our AlphaWise survey shows rising Airbnb adoption (now ~18 percent of travelers) with demand increasingly coming from hotels," the team, led by Brian Nowak, writes. "While still small, we believe Airbnb has been almost double the threat to hotels in 2016 than previously believed, and the threat is growing." The survey, in which more than 4,000 consumers from the U.S., U.K., France and Germany participated, was meant to gauge not only the growth of Airbnb but also the biggest sources of demand for the service.
