Disney Springs station most likely won't happen unless they institute a parking charge for Disney Springs, or they only run the line starting in the late afternoon.My dream vision for Skyliner expansion:
*A station at Disney Springs (buses are terrible there, and it would connect the resorts with boats to DS to the parks apart from buses
*A station at Coronado Springs (the Gran Destino Tower would be the place to be with alternative transport
*Shared station for the All Star Resorts
*Station between AK park and AK lodge with walking paths to both. AK is the only park with bus only transportation
*Walking path around Epcot from Skyliner station to Monorail station to connect the two for people without park passes or who only have single park passes and want to go to MK
I can see a system that ties AKL, AK, Coronado Springs, and the All Stars. Blizzard Beach at first blush would be a natural station, however people would use the free parking to go to AK.
Looking at the potential for walking paths between AKL and AK. And between the IG to the front of EPCOT Center. Both look doable. However, I think the AKL/AK path would be more likely.
