Holding company LLC

Jim,What is the purpose of your holding company actually owning the parks (well, owning the LLC’s that own the parks), particularly with parks you own solo? With each park in its own LLC, it already has it’s own “bowl” so to speak, so how would the holding company provide any additional protection? Obviously it makes sense if you have partners, but for parks you own alone it doesn’t seem necessary although I could be missing something!
