Ofc! I spent a summer raving before they shut the venue down. It was always so much fun.
Alcohol isn’t a big concern. A ton of folks are rolling and/or tripping so it gets hot super fast even if you don’t partake once you start jumping/dancing along you can pass out and water is always the first thing that sells out. I’m sure you’ll be fine though. You’re already plenty hydrated.
I think it’s totally badass that water is all you drink btw. It’s a goal of mine.
