Hi, Dan, thanks for your question. While you'll likely escape the Daytona Beach-sized spring break crowds, you will probably still see a lot of people. So be prepared. One way to be prepared is to call ahead and make campsite reservations if you can. Many campgrounds, especially the better ones, fill up during the winter.
Some campgrounds require a credit card number to reserve a campsite.
If you don't have a credit card and they ask you for it, you may be able to suggest the campground let you reserve the spot in another way. If a campground doesn't accept reservations, ask the best way to get a site, like arriving early in the day. A lot of Florida is on the Gulf side. In Clearwater, try Fort DeSoto County Park . Southwest of Gainesville is Waccasassa Bay Preserve State Park .
