Unless it was never really about keeping people on property, it was about making more money off charging for parking. Or Disney specific paid transportation (want to be minnie vans are back by 2022?).Something that makes no sense...
(Unless they are replacing it with some kinda of new "Paid" on demand service.. like Uber)
I mean, really, this makes ZERO sense for a few reasons.. Not the least of which is Disney wanted to keep people on the property, not encourage them to rent car's.
