It will rain and there will be a power failure. Prepare for both.
Ponchos and side walls for your EZ-Up (tied down of course).
Small car battery to run the fan controller(s), a quiet inverter generator if you need more power.
A very comfortable reclining chair so you can catch some ZZZZZs
Crocs for your feet. Super comfortable and OK if they get wet.
