If you have 5 connection "hubs" it could work.
1. TTC. This is the MK hub that would give service to the Magic Kingdom, Contemporary, Wilderness Lodge, Ft. Wilderness, Polynesian, and Grand Floridian.
(Connection to Epcot line near Ft. Wilderness)
2. Epcot: (Located in the bus drop-off). This would give service to Epcot, Boardwalk, Swan, Dolphin, Beach Club, Yacht Club.
(Connection to DHS line near Yacht Club) (Connection to DTD line near Port Orleans)
3. DHS area: Service to Wide World of Sports, Caribbean Beach Resort, Pop Century
(Connection to DAK line near Blizzard Beach)
4. DAK area: Service to Animal Kingdom, Animal Kingdom Lodge, Coronado Springs, Blizzard Beach, and All Star Resorts.
5. DTD: Service to Typhoon Lagoon, Saratoga Springs, Old Key West, Port Orleans Riverside and French Quarter, and the 3 Downtown Disney stops.
If you're at DAK and want to get to the MK...
You hop on at the Animal Kingdom...go to the DAK hub, remain on...and it will go to the DHS hub...onto the Epcot Hub...and continue on to the MK hub and on to the Magic Kingdom.
You never "stop" but it will continue to go through these motions to simplify the computer system and keep track of all of the vehicles. (If more pods are fluctuating towards the MK...then you can add more to that "route" and take some away from the DTD line)
