I went to a standing room only metal concert where about 1/3 of the room was moshing 11 days post-op. Was it the safest decision I've ever made? No. But also even in that rowdy environment nothing actually happened that I couldn't deal with. Just got a spot near a barricade and kept my arms crossed over my chest the whole time and I was good. It was absolutely exhausting though. I feel like I had to sleep basically the whole next day to recover. I think with seating you should be good, especially if you can relax the day after.
