Cordial is not a fluid. Senkajabin and diluted lemon syrup are both good fluids. A gallon a day of water or some fluid high in electrolytes is not too much. Drinking water is available on site, but if you have a discerning palate, you will want to bring jugs and buy it from a water vendor at a convenience store on your way to the site. There is a convenience store, about 2 miles from the site, and a grocer about a mile further.
Ice is also available onsite, but be prepared to pay for it.
There will be several food vendors in merchant row, you can even get breakfast there, and I will probably have coffee and War Cocoa available at my encampment, if ya wanna come over and say Hi. Drink lots of fluids. Attend a lot of parties. Wander around and meet a lot of people. Pound on your best friends with sticks and debris.
