I Recommend "CLUB NAPLES RV RESORT". It is the last exit on I-75 going south just before the toll plaza. Very nice, full of Snow Birds and our good neighbors Canadiens. Plenty of sunshine, pool, all kinds of activity. But you have to make you reservations early.
My wife and I stayed there for a couple of weeks in FEB 2010.
Bring plenty of $$$$$$$$$$. We want to keep Florida
