Feb in Florida is a tough month to find vacancies in campgrounds. You do not indicate whether you are looking to find places in state parks or private c/gs. Private c/g's are pretty much booked up for Jan & Feb, Feb being the busiest. You might find you would have more luck booking a month at one place and using it for a travel base. This would depend on whether you have a toad or not. Suggest starting by checking availability at inland c/g's away from the coast and heavy traffic resort areas. There are a number of large and very nice c/g's in the Arcadia area and again around Sebring and Lake Okeechobee. Good luck in your quest, we have all had to go through this.
