use google maps for three or four four Sundays prior to your visit to Fort Lauderdale around the time of day you intend to traverse from your hotel to the port. If you plot out your route, it will give you real time estimates of arrival and the traffic patterns on sundays. After 3 or 4 Sundays of doing this, you should have a good idea of how traffic delays are specifically for the route you will be taking. Another suggestion, would be to call the front desk reps on several Sundays prior to your visit and pretend to be staying in their hotel and asking them for a estimated time of arrival. They are getting daily direct feedback from their shuttle drivers and will want to be accurate if they think you are staying with them. I live here, if I was doing the drive I would give myself an hour and just relax at dockside upon arrival and not care abut the traffic. Bring a book, people-watch; enjoy our superb weather or walk to nearby shopping and while away the minutes before I am ready to face the ship's humongous check-in lines.
