Thank you all for your insight. Although we were planning to walk around a lot, we are travelling by car so we are stuck with it so to speak...
We will be staying for a few days and I have done my research on things to do, which seem to be more than plenty!
I guess we will just have to suck it up and pay the 32$. I saw online that the University has parking facilities which are cheaper but could not see whether overnight parking was allowed. And it is probably busy, so a parking spot might be difficult to find.
Right now this is the only negative in my planning. Looking forward to visiting Atlanta for the first time!
My dates are in the header 8/31-9/5
