Built in 1924 and shuttered since 1998, Bonita Springs' Shangri-La has the city's namesake natural waters on its grounds. This undated postcard says on the back: "An exquisite, year-round, vacation and health resort. The ideal place for vacationing, fasting, health rejuvenation, weight control, delightful vegetarian-hygienic meals. Pool. Boating. Gulf beaches."
