They should've sent you a map with the location upon your purchase

I’m not sure if Covid has shut that area down. You May want to check with the Atlanta Visitors Center.

Several large multi-story garages and a number of lots are in the area. You can't escape paying, street parking is rare and metered.

There is a directory of the bricks onsite. I havrn’t Used it recently but have no doubt it is available.

Yes, there IS a directory. But it can be difficult to get oriented. It will give you the section to look in. There was construction there when we attended. Take a picture of the directory map and use that to find your section.

yes

Not sure, I think it was near a free on some knoll. Can't think of where that could have been. There certainly is not a plaque.

Not sure... I took UBER to get around.

They are parking lots near the park some are free but I usually find a spot in the neighborhood and walk those 2-3 blocks back to the park.

Soweit ich mich erinnere, gab es keine kostenfreien Parkplatz in der Nähe. jedoch eine Vielzahl von Parkhäusern.
