The Castaways was a hotel and casino on the Las Vegas Strip in Paradise, Nevada. It began in the 1930s, as a small motel called Mountain View. It became the San Souci in 1939, and underwent several ownership changes in its early years. A hotel addition opened on August 21, 1955, when the property became the Sans Souci Hotel. A casino, showroom, and restaurant were eventually opened on October 23, 1957. These facilities closed less than a year later, due to financial problems, although the hotel continued operations. Following a bankruptcy reorganization, the shuttered facilities reopened in May 1960. However, the property soon closed due to further financial difficulties.
