I grew up at King's Island and now living just 2 hours away in Indianapolis I still get to the park at least once a year with my kids. And I can say I understand why they keep winning this award. Their kids area is spectacular. It's always clean, has good food, and tons of great rides. Add in all the Nickelodeon theming and some classics like Scooby Doo and what's not to like.
It might be hard for some to accept King's Island winning an award like this against the likes of Disney but their kid's area really is something special. If you have children that enjoy parks and are looking for something different to do this year. My kids get just as excited about visiting here as Disney or Universal. We'll be spending a weekend down there next month and they can't wait!
I highly recommend a trip to King's Island. It's a great park for families. And Cincinnati has a ton of other great attractions. You can easily plan a long weekend full of great fun there.
It's better in many cases than Disney for one reason. The Nickelodeon characters are far more relavent in todays kid culture than the Disney ones are. The rides are for the most part pretty basic stuff, but they are labeled well. Kings Island hasn't the money to deliver high dollar high themed experiences. It's all in the atmosphere and use of characters here, and it works.
