bike should be safe as most hotels down there have parking garages....it will also be easier to get around town and park closer to where you are trying to go....however cars are a good idea too because you can never tell when a stray rain shower will pop up down here....we have a great saying when people talk about the weather down here....Visitor says,"Damn the weather sure is nice today"....Local, in response says,"wait 5 minutes, it will change"
