This upcoming Friday says the hours are 6pm-11pm. Is this just the hours of fright fest or are we allowed in prior to this?

I believe its 10am to 9pm

On Fridays that is the time m Saturdays they are open earlier

As far as I know that is the park's hours for Friday's.

I am not an expert but I believe this is park hours. Your not going to get in before that. They probably dont have staff earlier than that when school and college is in!
