I have not attended an event there. Sorry, can't advise on this inquiry.
As long as it isnt sold out. I would show up at least 20 min early.
Check online. The person who I called last time with the same question was not too friendly on the phone, and she told me to get tickets online, so I would not block the line at the door. I ended up going there half an hour earlier, and there was no line, neither it was a busy evening. Plus she was slow as a snail, eating chips while she was handling my credit card... Thankfully the show was great.
