Hi, we went to MK for fireworks last 7/4...and the park stayed open for a few hours after the display was done. It was like E-night w/out the additional $12 fee. I'm not sure if it was just a fluke or they do it every year. Does US/IOA do the same thing? Or is it a hush-hush type thing...if you're there and hang around they may stay open? Anyone know?
