This is my streamlined route http://www.mapmyride.com/routes/view/46732616. Just under 15 miles each way. Plenty of Bike Lane or Sidewalk to suit anyones fancy. It's along popular side streets but never super congested. Going up and down the big roads are nice because the lights are longer for those cars then the ones in the side streets. Catch alot of green lights. Nothing to crazy south florida is pretty flat so its not to extreme.
