I don't know the answer to that since we live in Grand Rapids.
The park always tries to schedule the Halloween Weekend on the second weekend of October, but it would be best to contact the park for specific times for the events.
It was last weekend, sorry you missed all the fun! ;)
If I'm not mistaken I believe it was last week I'm here now and there's nothing going on this weekend. But I would call if I were you just in case they have something going on that I'm not aware of
