South Seas Island Resort is a 330-acre (1.3 km2) resort located on the shores of the Gulf of Mexico in the community of Captiva in Lee County, Florida. The original resort, South Seas Plantation, was opened in 1946 as a fishing resort by Clarence Chadwick, following a dry hurricane which ended commercial farming on the island. Chadwick owned much of Captiva and portions of nearby Sanibel, making his fortune inventing the Checkprinter in the 1920s. His heirs sold the property to Mariner Properties in 1966, which began the modern era of the resort. The original Plantation house, suffering from termites and wood rot, was demolished in the 1990s.
