According to market research firm PhoCusWright, last year 7% of hotel bookings were made via tablet and mobile phones (a figure 12 times larger than it was in 2010). By 2014, the number is expected to jump to 20%. According to a Harris International poll last year, 70% of those bookings are for same-day deals. "There's a changing behavior that's fueling this," notes Gerry Samuels, CEO of Mobile Travel Technologies, a company that specializes in mobile technology for the travel industry. "People are getting more and more comfortable making last-second reservations, not just in the hotel space, but in general." Samuels isn't convinced that the onslaught of last-minute booking apps -- most of which offer users cut-rate deals -- is necessarily healthy for the hospitality industry. "I think there is a really big risk of cannibalization. If a hotel loses the ability to control their inventory and who sees it, they can end up with the nightmare scenario whereby customers are re-educated to stop booking early in hopes of getting a better deal, and that can be very dangerous," he says.
