Is the Disco still in Mt. Olympus at Wisconsin Dells?
If by “disco” you mean the ride called the “Disco” the answer is yes! I just checked their website and took an interactive tour of the map and the “Disco” is in the inside amusement park called the parthenon in the Mt. Olympus theme park at Wisconsin Dells. If by “disco” you mean a dance hall the answer is no.
