You need to update your profile on the state park website. You’ll then have a 1 month head start on non-residents.

When you create your account in the reservation system (https://reserve.floridastateparks.org/Web/) there is a place to confirm your residency using your driver license number. Once you confirm residency then you can book 11 months in advance instead of 10.
