Being on the west coast of Florida a tent at least is a must. A towel is also a must as well. +1 on what everyone else said, keep things off the ground, have cover, invest in a really good fan, one or two spare shirts, and to keep things as light as possible (if not running in ears) put two speakers on sticks behind the band and as it will be low volume, feedback shouldn't be much of an issue.
Good luck!
Thanks for the feedback!
