I need some opinions on driving from Key Largo back to FLL on Easter Sunday for a 5:45 pm flight. We (family of 5) have never been to Miami Beach and are thinking about leaving early and driving to Miami Beach and then up 1A to FLL. We would go up the Turnpike and across the MacArthur Causeway and then up 1A back to the airport and possibly stopping to look around in Miami Beach. I am guessing that the traffic won't be too bad on a Sunday morning, but what about later in the day? What is there to see driving up 1A? Is it slow going? Would we be driving through safe areas? Thanks!
