More guests than ever are using apps to access hotel services, according to the most recent survey from the American Hotel & Lodging Association in partnership with STR, industry statisticians. The survey  showed the use of mobile apps to access hotel services is up from 35 percent in 2016 to 40 percent in 2018. It also found that hotels’ use of mobile devices as room keys jumped from 6 percent in 2016 to 17 percent in 2018; and mobile device check-in is now available at more than 80 percent of mid-priced or higher-priced hotels. Other findings included: higher-end chain hotels are more likely to have communal rooms with shared living spaces; and food alternatives such as a grab-n-go marketplace or similar pickup service have gone from being available in 21 percent of hotels in 2016 to 31 percent last year.
