Like other replies, parking closer to Jackson Square is hard to come by. I parked a few streets away and was able to walk over with no trouble whatsoever. WEAR YA WALKING SHOES if you plan to attend
It is not advisable to take your vehicle there. Like other replies, take the trolley, utilize a taxi/uber, or those bicycle/rickshaw things
Take a taxi or Uber/Lyft.
If you are lucky you might get one on the street, however the pay to park parking lots near the trolley tracks is your best bet.
