Our family will be renting a car in Washington DC early February 2014 & taking 2 weeks to drive to Florida.We have not yet decided on which route to take although we would prefer to travel inland.We thought given the time of year it may be wise to wait & see what the weathers doing. As far as what to rent? This is the dilemma.The room in a minivan such a 7 seater dodge caravan is appealing however if it's snowing I'm sure a 4WD would be safer to drive. As we can't predict the weather I don't know which way to go.No experience driving in snow nor living in such a cold climate, also unfamiliar with area. What would others do? 2 or 4WD???
