Q: What do USO and DLR have in common, which WDW hasn't quite figured out yet?
A: Both USO and DLR have theme parks that share parking structures.
EC and HS are close enough to do something similar. A new parking facility can be built in an elongated shape parallel to World Drive west of EC and south of where the EPCOT monorail turns east. The monorail could then be extended to run through the elongated parking structure and south a little further until it reaches HS. The new parking facility's like be used for both HS and EC. People would also be able to park at either the MK or the traditional EC parking lot and take the monorail to HS. In other words, the HS parking lot would be unnecessary with monorail being expanded. Only two thirds of a mile of additional monorail track would be required (comparable to the Hoggswarts Express), and a needle in a haystack when you compare the distance of track that was required for the EPCOT loop from the TTC. An extension to HS would not require a loop. The track would simply end just past the station and the trains would then reverse direction and switch tracks. Additionally, the elongated parking structure would also support the monorail tracks running through it, reducing overall construction costs.
