They don't normally let you "hang out" inside by the exit door. The security there is on point so you should be fine. Just stay right in front. I've walked to 1720 from another venue around the corner and I was fine. Just be alert as you should be wherever you go.
Not the safest place for sure. I would suggest waiting in front of the venue where typically others will be hanging out or going in/out of the venue and there should still be at least one security guard at the door. You might even wait just inside the venue at the exit door until the driver is just about to arrive. Ride share is the best option though because parking is rough and not the safest if you can't park in front of the venue.
