I rented the 3rd Floor Courtroom for our 12/31/16 ceremony and our 12/29 rehearsal - the cost is very affordable. One downside (or plus, depending) is there is no coordinator at the site, since not many weddings happen here But, I had a day-of, so no biggie. I picked up the building key on 12/28, and we dropped it in the box when we left the ceremony site.

I will say that getting a hold of people can take time, so start early and leave a window. The direct contact, Becky, always responded, but during busy times it may take a little more time. No biggie. Afterward, I did receive an email stating they were retaining our deposit, because they found beer cans (thanks, awesome guests!), but when I emailed back to apologize and ask for further info, I got NO RESPONSE. A letter was sent to my home, but still. Come on, now.
Regardless, it's a great location, especially for atheists/agnostics or other non/lightly religious people.
