We LOVED how our wedding turned out at the Yanney Park Cope Amphitheatre! We timed our wedding so that it would be at sunset. It was absolutely beautiful! We hung paper lanterns from the stage, but that's all the decorations we wanted or needed. The park is so beautiful by itself and the sunset made it ten times better. We estimated we would be able to seat about 150 people in the benches in front of the stage. We probably actually sat more than that. You could rent chairs and set on the sides of the stage or behind the bleachers, but unless you invite 300+, it's probably not necessary. We had a DJ do our music and it turned out wonderful. I highly recommend this venue!
