Ok, as far as I can tell, there are no Georiga or Georgia Tech games that day - so the Varsity shouldn't be over-run with people.
For anyone wanting to go to the Aquarium, admission is about $26 plus $9 per car to park. Not sure if they have any tickets available for that day, anyway. (At one time, they were booked months in advance, don't think it's that bad anymore).
I have a date to go listen to some Bluegrass music that evening... someone else's treating me to it, if anyone else is interested let me know and I'll find out about ticket prices and who is playing - it's some famous bluegrass guy/combo, but not
Allison Krause and Union Station - sorry!
EDIT: Here is the info!
