What is Saratoga Springs Resort like without a car?

We’re thinking about staying at Saratoga Springs Resort next year but a little concerned about the size of the resort. I understand that it’s very large. Is there a separate internal bus service to get around the resort? Has anyone stayed there only using Disney transport?

We didn’t have a car. We were near the bus stop. I walk alot. It was far from lobby. I walked to lobby and it didn’t bother me.
