Recently rode from Pensacola to Jacksonville along the Panhandle coast and then across the state. The state and national parks for camping are plentiful along the way, but you may need reservations during the busy months. The ACA route is more inland, but there is no reason to avoid the congestion along the beaches. Really only a couple areas that were bad, and the rest was pretty light traffic. Not sure what long term damage occurred from the hurricane, so you would want to look into that.
