Renting a car is the cheapest way to have fun when you travel because you are not dependent on cabs, which are very expensive especially in big towns and you also save money on gas instead of driving your own car to the place you want to travel. Rented cars usually are well maintained which means you will almost never have any trouble with breakdowns and since the car is not yours, the risk of theft is almost discarded because the rental company takes care of the matter and you lose no money.
Whenever possible we try to take our car. Our most recent two vacations involved driving instead of flying. We went to Savannah, GA and Orlando, FL from our South Florida residence. This fall we are planning to visit great Smoky mountains by car. So, whenever possible we try to avoid flights. That saves us money, gives us joy of long drive with scenic beauty. Whenever needed we stop the car, take pictures, give rest to body, etc.
