I recently went to KI for the first time and really enjoyed myself, I was there for one day and rode every coaster except the kiddies and invertigo.
Mystic timbers is incredible and the airtime is crazy, but I'm really disappointed at what's in the shed.
On another note I feel like some of the coaster there are not worth the wait, firehawk was uncomfortable, vortex was an arrow, flight of fear is rough and unpopular opinion here, The beast was not enjoyable.
Diamondback, Banshee, The Racer, Backlot Stunt Coaster, Mystic Timbers were great rides.
