But while Sea World is a marine life park, it's strength is maintaining a balance of rides, shows, and attractions. Many people would defer a visit if the park was simply animals with an expression of 'we've seen sharks and dolphins and penguins before'.
Sea World doesn't need a LOT of attractions - and lets face it, they don't have the room for them, but they do still need a core ride-base to keep those non-animal-interested people coming for those unique rides.
It's also not 'a wildlife based park missing a ride'... it's missing 3 - Pirate Ship, Bermuda and the Train (they ARE all rides)... Sure, they've put in the battle boats etc, but those took over an already popular waterpark area, so it's hardly a replacement for the three that are missing.
IMHO - SW needs to replace those that are gone with something else - and perhaps explore the options of attractions that extend out over the carpark, so save losing too much space inside the gates.
