The priority of any hotel is to serve its guests as best as possible. In recent years, that has meant concentrating on keeping them “plugged in.” As U.S. News reports, options such as mobile bookings, complimentary iPads for in-suite use, and smartphone apps for unlocking rooms have become standard fare in the hotel industry. Free WiFi is a given, and at some locations, guests can also adjust their room’s lighting, air conditioning, or window blinds using their smartphones.
