The Ambassador Hotel was the site of the Miss United States Beauty Pageant. The Pageant was hosted by Ray Raymond and sponsored by Belding Industries. Contestants registered for their room assignments, and roomed in the hotel's luxury suites with their chaperones. The Pageant itself took place in the hotel's auditorium. Jaime recovered a stolen microchip in the hotel's car park after a bionic tussle with a car belonging to Raymond and his henchmen. (Bionic Beauty)
