Also, if you're renting a car, please make sure you know where you are going and Heaven forbid go way under the speed limit. Lots of tourists seem to go slow, maybe it is because they are seeing the sights or are lost etc but keep in mind that many, many people, including me, commute down from FLL and even PBI to Miami for work. Traffic is bad enough already, please do your part to keep it moving.
