When the Castles returned to the U.S. in 1912, their success was repeated on a far wider scale. Making their New York debut at a branch of the Cafe de Paris, the duo were soon in demand on stage, in vaudeville and in motion pictures. In 1914, the couple opened a dancing school in New York called "Castle House", a nightclub called "Castles by the Sea" on the Boardwalk in Long Beach New York, and a restaurant, the "Sans Souci".
