ALAMO on site location how to get there

[frijole]

I have care booked with Alamo at the Car Care Plaza which I think is sort of in the center of the world not far from Epcot. They offer shuttle from hotels but I want to take break from parks, go get car late in day, take it to hotel and drop it and then meet up with party back in park. Does any Disney transport stop at the Care place or it walkable from one of the regular stops. I chose this because the Alamo office in Dolphin closes so early it is not pratical to get the car.
