Steelhouse Omaha

This weekend I am going to a concert alone and at a place I’ve never been to for the first time ever. Steelhouse. I have a couple questions to help ease my anxiety.

1) I have a standing room only ticket but when I bought them the map looked like the standing room was the same area as general admission, but GA was a higher price. Can someone tell me what the difference is between standing room only and general admission at Steelhouse?

2) How is parking? Any recommendations?

Thank you fellow Omaha people.
