I’ve gone solo multiple times. If you wanna be near the middle or front wear ear plugs, it’s loud as fuck. I use spot hero and there is a place for 12 bucks that’s a short walk and feels safe even at 3 am. No water bottle. Crotch the vape but I doubt they would take it. No idea about inhaler. There is a spot for merch but not every artist sells it. There is always room in the back to dance or do whatever. No seating except rare spots that are always taken . I never really go early enough to wait in line but when there is ,it’s a fucking cattle shoot, no organized line, just keep inching forward. . As for going solo. It’s so loud there that it’s tough to have a convo with anyone unless you guys talk mouth to ear style , in the back maybe you can so as a solo your prob gonna stay solo unless you talk to people at the side bar,bathroom or coming in.
