It's one of the great debates in travel: Should you book plane tickets or load everyone in the car? Obviously there are places where driving is not an option (say there's an ocean in the way). But what if you are staying within the continental U.S. to take the kids to grandma's or a theme park, or you are making a getaway to a romantic resort or the big city? We put flying and driving up against each other in a battle royale, taking into account time, money, convenience, and safety. Both sides make persuasive arguments. Now you can be the judge. Tell us in the comments which you think is the winner.
