If you have kids that are less than 48" tall, the Coney Island rides are the best bang for your buck. If you go to Kings Island you will be disappointed with paying a huge admission price and then being trapped in less than ¼ of the park (because that’s the only place your kids will be able to play). At Coney, kids that are just 36” tall are allowed to ride some pretty good rides with an adult (much better rides than Kings Island, which has much higher height requirements for similar rides). It’s quick, cheap and easy. You can do everything in just a few hours (your kids only last that long anyway).
