This left the fair board and Six Flags to negotiate the ownership of rides and attractions. On July 25, 2010, this dispute was settled with Six Flags receiving a ride of their choice (Road Runner Express), and $2.8 million in lease-related payments owed by Six Flags was forgiven in exchange for Six Flags' property rights (which included the offices, furniture, fixtures and equipment relating to the park, and all intellectual property). The Kentucky State Fair Board also used $2.35 million from Ed Hart to purchase Six Flags' stake in the park. Six Flags removed all of the Looney Tunes and DC Comics/Batman related content from the park along with inner tubes, overhead shades from rides, and some parts from rides to use at its other parks.

After 16 months trying to get funding approved, the Kentucky Kingdom Redevelopment Company announced on September 30, 2011, that the fair board had ended negotiations and that their company would no longer take part in reopening the park. On November 4, Ed Hart sued the state of Kentucky in an attempt to recoup $1.4 million that he claimed had been spent as part of the failed effort to reopen the amusement park. On January 16, 2012, the owners of Holiday World & Splashin' Safari in Santa Claus, Indiana, announced they were involved in talks about the future of Kentucky Kingdom. Their media release stated they were in a fact-finding stage and hadn't made any decisions about whether to move forward in pursuing an opportunity to run the theme park. On February 7, four members of the Koch family, who also own Holiday World & Splashin' Safari, formed a new company, Bluegrass Boardwalk, Incorporated, to negotiate a lease agreement with the Kentucky State Fair Board and to apply for economic development incentives from the Commonwealth of Kentucky. On February 23, the Kentucky Fair Board
