We bought our season passes and parking pass last October and went to Fright Fest 3x. We have already made up for the cost of all the passes so all visits this year are free. We went to the amusement park 2x so far and the water park 1x so far. We are planning another water park visit in July and 2 more at least in August. We will probably go the Fright fest 3x again, especially since it is starting 2 weeks early this year. Opening weekend is a bring a friend free weekend and there is a coupon for one free haunted trail.
I also bought a season pass for the go karts in October last year.
