AI and machine learning already are impacting operations significantly: Hoteliers using chat bots and AI-supported concierge services reported that 70 percent of guest inquiries are being answered by such systems. That shift is yielding clear benefits, including relieving employees of mundane tasks. In addition, according to the study, one-third of all queries are answered more quickly, thanks to the use of AI solutions. Ultimately, that translates into better service and happier guests.
