I just finished my first six months of full-timing, and my first winter in FL. After reading all the warnings on this and other sites about the difficulty of finding parking in FL in the winter months, I have to say it was not nearly as difficult as I feared. Due to my work, i didn't know my itinerary more than a few weeks in advance at best. Looking just a few weeks out, I found that there was always some reasonable place to park near enough to where I needed to be. It may not have been my first, second, or third choice, but there was always something reasonable available. From Jacksonville to Naples, I moved every couple of weeks. Lots of places had something they called "overflow" or something like that. They may not have been the prettiest sites, but they were good enough - usually located near the entrance, which I liked.
