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 etc etc.
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.
