Whether that number would quadruple when Airbnb starts offering Experiences in 200 US cities remains to be seen. If it does, then it would be great source of income for the company, which takes a 20 percent cut from the activities listed on its website -- especially since a lot of them aren't cheap! As FastCompany notes, Airbnb is likely hoping that an Experience can persuade people living, say, a couple of towns away, to go on a weekend trip they'd spend at home otherwise. The expansion could get users to travel more frequently, since there's something to see nearby, and could also create new customers in those who'd rather not wander too far from home.
