I am not generally big on concerts but as far as venues go this was a fantastic environment.
When we arrived the line moved quickly because there were several people spaced out along the entrance doing separate jobs. First came the pat down, then the ID checks for those who want to drink and finally the ticket scanning. I think this made everything move faster because the people at the front reminded patrons to have the tickets out and ready several times before they were needed.
As soon as you enter there is a bar on the right with a large selection and typical painful venue prices. Then there is a path all the way around the stage that the bouncers kept clear the whole night. I would love if bars did this! Whenever I wanted to move to another area (bar, bathroom, outside) I had minimal crowd swimming to do before I was free and clear to move about the open walkway. We spent our time at the raised deck in the back. View was a little removed but it meant we could see over everyone's head which I thought was better.
The only two downsides were that cleared the outside area abruptly before the night ended. We had gone out to cool off for a moment and then were sent almost immediately back inside in a brisk manner. The second downside was that even though there were several bars service was slow.
*protip - going all the way along the side to get to the left hand stage before the bathrooms is a fantastic view of the artist. You can't stand and gawk because they keep the path clear but you can definitely get a quick view and pic!
