Outside of the normal stuff, I've started bringing a blow up mattress and a few pillows. Clutch for spectators or even yourself between sessions. I use this one now and it works better than others I've tried because it is 'double high' and can be used as a bench seat also.
Here, get it for $50 bucks: https://www.amazon.com/gp/product/B000M0MJU2/ref=oh_aui_search_detailpage?ie=UTF8&psc=1
