Washington ( CNN ) -- The Hilton hotel chain has reached an agreement with the federal government to make changes in about 900 hotels nationwide to further accommodate guests and visitors with disabilities , the Justice Department announced Tuesday . The agreement covers the Hilton hotels built since passage of the Americans With Disabilities Act in 1993 . It includes making changes to Hilton-owned hotels under a variety of trade names including the Waldorf Astoria , Embassy Suites , Hampton Inn , Doubletree and Homewood Suites . Government lawyers had alleged Hilton failed to provide an adequate number of accessible rooms , failed to disperse accessible rooms among the various categories of available accommodations and failed to provide individuals with disabilities the ability to reserve accessible rooms through its reservation system .
