Good campground near Jacksonville,FL

Tried calling Flamingo Lake. they don't take reservations until 30 days in advance. Said they don't get as many snowbirds so they generally have open spots. also they are building about 60 more sites for Monthly stays. should be done later this year, and available in April when I plan to be there. so right now my plan is to wait till March and get a reservation at Flamingo Lake. But I'll have a plan B just in case.

Thanks everyone for your comments. Very Helpful.
