There are 2 nearby surface lots. Both about 1.5 blocks away. One is on Ross (not recommended) and one behind the red brick church back towards Woodall Rodgers. Also, underground parking lots under both the Performance Hall and the Opera House. Underground is more expensive but better protected.
Parking garage underneath the facility...platinum parking I beleive. Open lots directly across the street also.
The closest and easiest is in the street in front of the theater in each case, with free space. The best for me is the one that coinside with the same theater below it. but there are several parking options in the area.
