Each property falls within one of seven reward categories (number 1 through 7, with 7 being the most expensive), except for Waldorf-Astoria hotels, which belong to their own unnumbered category. To determine the reward category for a specific property, see the home page for the individual hotel's website. (For instance, the
Washington Hilton website shows, under the "Our Hotel" heading, that this is a category 6 property.)
The HHonors website also provides a search tool for identifying properties in a given category within a specified US state or foreign country.
