The park really only needs like 3 coasters (wing rider, hyper/giga, rmc) and it would have one of the best lineups anywhere...
I'd love to see a ride like Escape From Pompeii added too...
But what the park REALLY needs is more things to do indoors...the park practically shuts down when it rains. A few dark rides, more indoor shows...more indoor animal exhibits...anything to keep the park alive when it's pouring rain.
