I'll say this as simply as possible - Celebration City is one of my favortie amusement parks. I really like the place. They have a world-class wooden coaster with the Ozark Wildcat, the have one of the most intense flat rides going in Fireball and they have what may be the best nighttime show outside of Orlando. And that's just the start.
The park has a wonderful look and feel to it - plenty to do, but laid back. The folks working at the park are among the friendliest I've ever encountered at any amusement park. They have animal shows, games, a lego play area and even free go-karts.
If you ever visit the Branson, MO area, be sure to stop by Celebration City. If the park wasn't good enough itself, Silver Dollar City is just a few miles down the road and admission deals for both parks are readily available. You'll be hard pressed to go wrong with this one.
