Yeah, that's what I mean. I personally haven't been to KI since 2015 (now in NE OH, but grew up in Dayton), but I know even Mystic Timbers has that "fun" factor. I say that based on the many other GCIs I have been on. You just want to re-ride over and over again. I get that same feeling on MF, SV, TTD, to name a few.
However, like you said, Valravn and GK are cool rides. I like them, but I am satisfied with my trip to CP if I get to ride them once. If I only get 1 ride on SV, I am disappointed and don't feel fulfilled. Maybe I am just greedy though.
I guarantee, this will be one of those rides that you keep saying "ONE MORE RIDE!"
And as a side note, I just watched POVs from Leviathan and Fury. They each have a tunnel of some sort so I think there's a good chance this new Giga will as well.
