In between Marriot's stint and Paramount, the city of Santa Clara
owned the park and it was run under contract by King's Entertainment
, owners of other parks such as King's Dominion
In addition to the rides, GA has(had?) a dolphin show, two "live" theaters (live dancers/singers, tracked sound usually) an IMAX theater, and an outdoor concert pavillion.
The theater in Orleans Square always has a dance revue, as it isn't all that large. It has alternated between being tracked and having a live band. Grand Music Hall is the larger theater, and has often served as home to an ice show, performers were contract and not GA employees.
