The management of Great Adventure had not expected the success of the attraction and did not pay it much attention. Despite this, the Haunted Castle became the park’s largest single-show attraction since its construction. During peak attendance times both sides of the attraction would be in use, and thousands of visitors would come to the Haunted Castle throughout the normal hours of operation. The original planning had been to treat the attraction as seasonal and disassemble the trailers and send them back at the end of the season. Because of its unexpected success, it was decided instead to extend the lease and add it to the list of permanent attractions.
