I think that Adventureland should be left alone and (maybe like what was mentioned on a previous WDW Radio Show) redo the old River Country water park in Fort Wilderness and turn it into a type of pirate hide out. All the overgrown shrubs, "wild" areas would be fitting for a pirate lair or hideout. Maybe even incorporate a POTC/Tortuga "looking" restaurant where everyone who loves the ride and the movies could escape. Maybe even moor the Black Pearl in a man-made lagoon for a scenic, yet unapproachable, view in the bay. Other ideas --- overnight or late night kids' club with the pirate theme, adult nightclub, or even a Pirate themed camping area ???
I guess with Disney, the possibilities are endless !!!!!!!
