I think they should use the northeast corner of World Drive and EPCOT Blvd to place a very giant, triple-deck, circular/helical, multi-million dollar bus terminal hub. This would effectively be the new WDW transportation hub - non-accessible to cars, taxis, or Uber. It could have a monorail stop (maybe). All buses that go to and from any non-theme park would go here. That is, if you want to go from MK to Caribbean BR, or from MK to Disney Springs, or AK to Polynesian - you would board a bus from those locations to this hub, then change a bus at this hub to your destination. This particular spot is central and convenient to the entire property.
