I would sell to either cedar fair or funtime
If he still owns Circus World and Great Adventure I'd have him sell them to Cedar Fair. Or one to Cedar Fair and the other to Funtime.
Revolution Studios is currently negotiating with Luna Parks to use the DiC characters at Worlds of Wonder in Nevada. Luna will have to make a separate deal with the Ludwig Bemelmans estate to use Madeline, to which Revolution holds the screen rights. but I am not too sure how that property could translate into a park attraction.
Additionally, Luna, along with two other park chains are speaking with the family that owns the Berenstain Bears characters.
Madeline, the DiC characters*, and the Berenstain Bears would work in the ubiquitous kid's area of the park.
*Whatever that nebulous phrase covers.
I think i got a better name for last frontier. Last Funtier. Also i dount worlds of wonder would be in the name du to copy right reason
How about Trump's Great American Wonderland? Which would then be changed to Worlds of Wonder Last Frontier when Luna Parks gets it and scrubs off the Trump brand.
