Maybe i'm whack, but if I think theme park for immersion I have to say DAK is #1... I just love the theming... I know rides wise it's a bit of a dud, but my god that park is GORGEOUS. I consider it one of the most lovely outside of Disney Sea.
Don't get me wrong as I really do love IOA... I don't know what my list is tbh. I just never saw it as a #1 in Orlando.
