The State Parks will be filled up with Snowbirds, you'd be hard pressed to find a spot. IMHO, JMHO no great loss because I found the state parks a jungle, bug infested and VERY VERY small sites, and unlike most State Parks they are not cheap in Florida.
Take a look around the Dunnellon, Rainbow Lakes area. There are some IMHO GREAT CG's in this area. Took me 4 years to find this hidden gem of an area. Beautiful blue springs parks one does have a CG. Not right on the coast but a short drive to the Gulf. This area is the old Florida clean nice and a lot to do within a few minutes of driving.
Look up the Cedar Key area CG's are right on the gulf.
In answer to your question? YES, the snowbirds will all have already taken all the good spots and hunkered in for the Winter. :W
Good luck, you will find a spot. My first 2 trips down I didn't make reservations anywhere and managed to find nice CG's. I just will NOT do Central Florida anymore since I found out about this area in the N/W central.
