Not sure if you saw what I wrote, or if we were basically writing at the same time. But this is what I mean. USF and IOA were built with expansion plots and ideas of what could go in them. Some went according to plan and some did not. JPRA was to be a taller ride when it was going into USF, but got scaled back a bit to fit into the budget of building a whole new park from scratch.
IoA was a complete park when it opened, some say USF wasn't but because of technical issues. Hopefully they've learned more from both experiences. But now let's take a second to laugh at the tram ride they scrambled together which half of it was hey look at the attractions you could be doing if you weren't on this dang tram ride
