I thought they would go with a proslide flying saucer coaster like they are doing at water country. This might have required them going over the exit road for most of the layout. But the site plan drawing appear to eliminate that idea.
With that said, it appears they are working with proslide and this foot print would fit one of their tornadowave rides. This would give them the only tornado slide in central Florida, maybe. I say that bacause I think Margaritaville's new water park was show a tornado slide on their original plans.
