southwest Florida winter 2018

I found last year that as the season began without being full the CGs became more flexible. I would think that capacity may be reduced this winter because of the storms.
Not as warm, but the western FL state parks had availability last winter. There are several between Panama City and Pensacola.

As Becky says: wait till the season begins. In the last five years at our park something always happens and sites become available. You are talking about a SENIOR population mostly. The coasts are definitely harder to find spots than in Central Florida but still I think you will find something: maybe not the best site but something. Good Luck

Kathy is speaking of "Southwest Florida," say from Tampa down to maybe Fort Myers.
