First off, this is insanely huge news and changes a lot of the national map yet again. The balance of power in the domestic amusement industry is, once again, massively upended.
Secondly, I REALLY like Palace in Herschend's portfolio. I've been to Lake Compounce, Kennywood, Idlewild, Dutch Wonderland, and Adventureland and think all are somewhere between surprisingly good to great but, at the same time, all feel like they've lacked consistent vision, investment, and support. If Herschend can keep standards high, some of these parks almost certainly stand to benefit GREATLY from this merger—Kennywood being the most obvious.
Thirdly, there's a lot of, well, uh, trash, that comes with this merger—mainly a disparate array of small water parks and FECs that, while probably technically profitable, really aren't in Herschend's current wheelhouse at all. I could see Herschend selling off a good handful of those properties over the coming years potentially opening up the opportunity for Premier Parks, Merlin, United Parks, or others to grab a few interesting, smaller properties—possibly for conversion projects. Plus, since Herschend's territory is far less expansive than the newly-merged Six Flags', I don't think Herschend will have the same adversion to selling parks as operating parks that new Six Flags almost certainly does.
Though there are other angles, I want to share two I've thought about previously related to United Parks. Wet 'n Wild Emerald Pointe (the other, original Water Country USA) could make a compelling Sesame Place conversion (if the chain is still interested in those). Greensboro would a good fit for a children's park and it would greatly extend BGW's/United Park's footprint into North Carolina as better competition against Carowinds over the booming Triangle area. Meanwhile, out in Hawaii, there's a little-known marine life park named Sea Life Park that is already something approximating Discovery Cove or Discovery Point. It would make a TON of sense in the United Parks chain.
Anyway, probably a bit early to be parting out this huge, new chain, but I do think that many interesting doors are suddenly open all over the place...
