Whilst they are at it, Disney should demolish Sleeping Beauty's Castle because it has been there for a really long time...
The castle at Sea World is sadly another case of Sea World neglecting what was once an icon (much like the light house). I am with you, going by the recent trend at that park, it will probably be unceremoniously removed, much like the light house was, but what could or would they put in that location? I mean, it would give them a chance to help flatten that area, perhaps even re-work the pathways around storm, they could fill in the splash down pool for Vikings and make the area more and easily accessible.
