The Adler Hotel, also known as the Hotel Adler, was a 150-room, five-story hotel in Sharon Springs, New York, that operated from 1929 until 2004. Known for its therapeutic sulfur spa, it catered primarily to a Jewish clientele who travelled to Sharon Springs in the summers. It was kosher, with two kitchens. It was built in the Spanish Colonial Revival style and was adjacent to the Pavilion Hotel, which had been a summer destination for guests such as the Vanderbilts, Rensselaers, and Oscar Wilde. Ed Koch worked as a busboy at the Adler Hotel in 1946. When Steven Spielberg was preparing for Schindler's List, he interviewed survivors staying at the hotel.
