Great location for arena events. Centrally located in the city and works well for monthly commuters. I find the garage has easy entrances and exits either onto 5th street for 6th street. Even when it seems like a line to get it, it moves fairly consistently.
The garage has definitely seen an uptick in daily parking traffic. They are competitively priced with the in by 8:30 deal being $6 per day currently (April 2015). With the uptick in usage, I do find that I have to drive to a higher level. But hey, it's the city what can you expect.
One unique feature in this garage is the spiral entrance. Until noon or so, you can drive up the spiral and pull directly into a higher floor. So no weaving floor by floor. Then afternoons the spiral changes directions and you can head straight down. I only know of one other garage in Charlotte that has this (BB&T).
Another unique feature is that you can walk through the Wake Forest garage and the 1 BAC garage into the 1 BAC building. Completely covered for those rainy days. Look for the skywalk on the 4th floor.
Finally, the deck does get messy after large events with trash and such. But I see a janitor going through picking up fairly frequently. It's probably due to the higher amount of traffic and proximity to the arena.
