6. There Was An Automobile Showroom in the Grand Ballroom of the Hotel
The General Motors Motor Show, which was then known as “Motorman,” was showcased in the Grand Ballroom of the Waldorf Astoria from 1931 to 1961. There were no car dealerships in the city back then, and this was a way to showcase fancy prototypes and concept vehicles to the public during the New York Auto Show. The Grand Ballroom is four-stories tall which not only housed auto shows, but could also seat 1,500 for dinner or 1,100 with dancing.
