We like Salt Springs State Park in Ocala National Forest. Look on Reserve America. You might be able to get a couple days during the week. Search for approx dates and if no luck, click on "find next available date", then scroll down to see availability. I found some spots for 3 days. Not fancy but beautiful spring. Last time we were there, cell service was limited so you will need a booster or drive to make calls. We also like Rainbow Springs State Park at Dunnellon. It's been remodeled and now has full hookups. Again you will only find a couple nights at a time, during the week.
