With more than 80 rides and attractions, the 364-acre Kings Island amusement and water park, 24 miles north of Cincinnati, is sure to make your brood smile. This year marks the 30th anniversary of the world's longest wooden roller coaster, the Beast, as well as the grand opening of Diamondback, a new death-defying roller coaster. Plus, you can enjoy more than 30 water slides in the Australian-themed water park Boomerang Bay.
General adult admission typically costs $48, but you can save $15 if you purchase your single-day tickets online. However, if you pay the full $48, you can visit the park any two days during the regular season. And for an extra $13, you can get an all-you-can-eat picnic meal.
