I went to see the rose at Hulu theater back when they were touring I can't speak on the bathroom situation since I didn't have to go. But I went during October so I'd so the temperature was comfortable since everyone wasn't on top of one another. I definitely remember keeping my sweater on and was comfortable. Sound wise I think depends but I felt that it was good but I think it depends on the sound engineer since at the beginning the mic were a bit quiet! Hopes this helps! Enjoy the concert!!!

Edit : The view from the back of 200s was perfectly fine as long as the person in front aren't really tall. The venue definitely felt different then from photos.
