If money and feasibility were no objects, what ONE major change would you make to the resort to improve expansion possibilities, guest flow, etc.?
Move the entirety of Adventureland (JC and Indy) to north of Frontierland so that it can be expanded.
Move the Grand Californian so that DCA can expand to the NW.
Reroute Harbor to the east so that Tomorrowland can be expanded.
Build some kind of transportation that encircles DCA, ala the DLRR.
