I camp at Pennsic each year, which is in PA not FL so some of the advice may not be transferable. I hope some of it helps, though!
1) Bring doubles and triples of everything related to keeping dry, keeping warm, and keeping your tent secure
2) you can never ever have enough tarps, towels, sheets, blankets, socks, or really anything
3) Bring a heavy blanket - it can get cold at night. And 55 degrees outside in a tent is a VERY different thing that 55 in a house
4) Bring layers, for the same reason as above
5) Plan for all weather, really, as much as is feasible
6) Make sure you have a lot of snacks that aren't salty or chocolate-y or gummy. You get hungry while camping! Dried fruit chips are a favorite of mine
7) Take ALL of the water
8) Bring more things to do than you think need. I bring books and magazines, my phone, an Anker charger and some crafts to do
9) Create a set up that is easily maintained and secure so that you don't have to constantly adjust tent lines and the like
10) Bring more tent stakes than the tent comes with. You WILL want to secure the tent extremely well, and most of the pegs that come with tents are cheap and will break
11) Don't sweat small stuff. Things are gonna get broken, muddy, lost, etc. It doesn't have to ruin things.
12) Take the bed off the floor if you can. Get cots or a cheap futon frame. It makes a HUGE difference
13) Have fun & be safe!
