I honestly don't know if they are popular among the general public the one at MoA always has a decent line when I go there. I don't go there often. It is a really good one though
they could make it an inverting coaster. and they could make a nice new log flume ride where the amphitheater. and yes that is all way too expensive for cedar fair to put at their second smallest park.
This is just total speculation and has no evidence. but I think they should remove corkscrew and wave and build a compact blitz coaster or something like that on the same site.
