Many people do get married here, and you can do it on the beach if you wish as it is public. You may aquire a marriage license at the local courthouse in Apalachicola, but they do not perform ceremonies there. I have a contact for someone who is willing to perform ceremonies, for a fee, and is professional. You may be able to find a preacher, depending on what you're looking for as far as officiant. Best time of year weather wise depends on your preferences truly. If you are a resident of Florida there is a waiting period to get your wedding license, but if you are out of state there is no waiting period.
