NEWS: The Beach Waterpark Reopens in Theme Parks, Roller Coasters, & Donkeys! Posted May 31, 2012 ^No. Why would they? The majority of their slides are OLDER than Kings Island's waterpark as a whole. Besides, none of their slides was something to write home about...The Beach was like a water park "fair". And yet, a day at The Beach watermark was always more fun for many of us than kings islands waterpark. It just had a less hectic atmosphere about it. And the tube "slides" were really good, nothing like it at KI's waterpark. Prices were better and the platinum pass was an awesome deal. Free soft drinks and tube rental if you got there before noon, not to mention prime seating by the wave pool. I'm truly sad to see this park close.
