Despite Ayres's efforts to improve its Indianapolis flagship store, the city's downtown had declined by the 1970s and the West Washington Street store was surrounded by empty lots and vacant buildings. To encourage economic development of the area, Ayres and others invested in two downtown hotel developments in an effort to attract convention and tourism business. Ayres contributed $3.3 million to development of a downtown Hilton Hotel, which later became a Sheraton Hotel, and $50,000 to the Merchants Plaza project, where a Hyatt Regency Hotel and Merchants Bank offices occupied most of its space.
