  • Publication number: 20060173617
    Abstract: A product location display system and method are provided that allow travel related product information, such as the geographic location of hotels, to be displayed on an interactive display. An application server of the product location display system receives user inputted criteria for a travel product search. A location management system determines a location for the travel product being searched based on the inputted criteria. Sub-locations associated with the geographic location being searched are pre-defined as being within the searched geographic location and stored within a location database memory component coupled with the location management system. A display configuration component of the location management system arranges and displays results of the search for the travel product by the sub-locations defined as being within the searched location.
