My first choice in the Destin/Santa Rosa Beach area is Topsail if you can get a reservation, it books up really fast. Some times of the year you have to make reservations 11 months in advance. In the Gulf Shores area, Gulf State Park with 496 sites with full hook up is good. This time of year they allow snow birds to book about 250 sites for the winter, so advance reservations here is needed. You better make plans ASAP.
I just got back from both locations recently.
