The park will be 10 years old in 2 years, so hopefully they'll finally get to an expansion by then.
I wonder if the issues they've had with the slides is a factor in why we haven't seen any expansions yet. I'd imagine they're going to be more cautious before they add any more slides.
Was this hidden down a path somewhere? The Mystic Fountain still gets a decent crowd frequently but it's easy to spot it passing by, and once a couple of people gather more follow. Was the placement of Vol not as accessible or visible?
