We just got home from a week at Bryn Mawr RV Resort in St. Augustine. It has several spaces on the beach but make sure you reserve to make sure you get an ocean spot CONFIRMED. 40 miles north of Daytona, St. Augustine has a lot to offer in the form of site seeing particularly. Bryn Mawr has a security gate at the entrance. They also have security gates leading from the resort to the beach. The gates give free access from resort to beach but you must punch in a code to get back IN from the beach. Very secure place. Only shortcoming is sites are a little tight and the streets are dirt/sand surfaced. We'd go back in a heartbeat because there's so much to do in the area. Good restaurants too.
