Wireless Internet access, or Wi-Fi, is nearly pervasive at U.S. hotels, according to a new survey of hotel executives conducted by the American Hotel & Lodging Association. Eighty-six percent of hotels now offer Wi-Fi, and about one-fifth of the remaining hotels plans to add the service within the next five years, according to the survey "Current and Future Use of Technology in the Hospitality Industry," released in June. Wi-Fi deployment is about equal at chain hotels versus independent hotels (87% vs. 84%).
