If you were wondering this summer if it was cheaper to fly or drive on your vacation WELL I have the perfect website. It is a calculator on the BeFrugal.com website. http://www.befrugal.com/tools/fly-or-drive-calculator/
Besides the information you would expect, it incorporates the number of people traveling, the make and model of your car, price of your hotel rooms, tolls, taxis, rental cars, baggage fees plus more. It is really well done!
So take a minute and check to see if it pays to fly or drive!
