Company spokesman for the Hard Rock said the park laid off between 20 and 30 full and part-time workers earlier this week.
The park's hours will also change after the Labor Day weekend, just opening Thursdays through Sundays from 11 a.m. to 7 p.m.
The park will also close for the winter on November 2, but that could change depending on attendance.
Hard Rock park plans to reopen in 2009, but hasn't set a date.
