Before becoming Latitude 20°, this was The Polynesian (1957-1964).
The Polynesian opened in 1957 and closed due to fire in 1959, but was refurbished and re-opened in 1960 to run for 4 more years before being sold in 1964.
Hop Louie re-opened it as Latitude 20° on July 15th, 1966. Latitude 20° ran through 1980 before being sold to developers who decided to stray from the Polynesian theme and go Country. It was a Waco's and then a Calamity's before the structure was finally leveled in 1984.
