We have stayed at Camping on the Gulf in Destin several times. We always camp in the second row from the Gulf. The first row does not have sewer. Water and electric only. They will pump you out as needed ($). The second row has water, electic and sewer.
As already stated they are pricy and you will get sand in the camper. The up side is you are just a few feet from the ocean. Just walk a few feet and dip your toes in the Gulf. Several times I have set in the MH and watched dolphins swim by. Where else can you do that?
