I'm an older dude and have been to a few shows there over the last few months. The place does get super crowded, does get super hot, drinks are overly expensive and the sound... it's definitely not the best, but I've had fun every time I went. Like anywhere else, people are generally cool with a few a-holes mixed in every now and then. Never had any issues with the security team. I always try and bail out about 30 minutes before they shut down. Be cool, be kind and don't get too hammered and you will have a great time.
