If you want a route that goes along the coast beginning near the panhandle of Florida, send me a private email and I can send you a cue sheet and some GPS coordinates.
I rode the route from Wauchula (on the ACA Florida Connector route) which is near Tampa to Pensacola and some friends continued onto Baton Rouge to reconnect with the ACA route.
The difference is that there is more traffic (not unbearable), and more beaches. Due to my preference of staying on lower traffic roads when possible, there are more turns probably than the ST route. You also get more services but the services are probably more expensive due to being near the beach.
Also, if time/money permit, I would HIGHLY encourage riding on the Florida Keys. Again, more traffic but it is nice.
If yonovice a noive cyclotourist with limited experience riding in traffic, these routes may not be the best for you. They are not bad at all but if you prefer seeing only a few cars every hour, these are not the routes.
Whatever you choose, enjoy the ride.
