we liked Topsail, near Destin. We also love, love, love Rainbow Springs just south of Ocala. Great tubing & canoeing. We have been to Manatee Springs...nice....lots of deer going right through your campsite....and you'll see Manatees in the river. Blue Springs is right outside Orlando...that was nice, but we went during the summer, so we didn't see the Manatees. Anastasia in St. Augustine is WONDERFUL. Hillsborough River State park is really nice too. Really liked that. Ft. Desoto is great....whether you have the yappy dogs or not...like you said, there is a "no dogs" campground and a "Yappy dogs" campground. We like the yappy dogs side and the great dog park and dogs allowed beach....(there is also a "dog-free" beach. We have been camping in FL for the past 2 1/2 years and have found almost every state park to have something unique. Enjoy your stay!
