Renting a car at your destination may be a requirement to get around or it may expand your vacation horizons beyond the immediate city limits. It is often nice to have your own transportation once arriving in a city, and it isn't difficult to find a cheap rental car deal.
Check as many sites as possible for prices. Expand your search beyond compact car to catch special sales that may apply only to a larger car class, getting you more car for your money.
Look for rental locations near, but not at, the airport. But if you are renting from a location that isn't located at an airport, be sure to check the company hours as many locations may be closed on Sundays. Because you can often find discounts on weekend car rentals, still consider these locations for Friday-Monday travel to get the weekend deals.
Be aware of age restrictions for renting a car. Most rental car agencies will require a minimum age of 21 for the driver. If you are 20 years old then try renting from Hertz, who will make the allowance.
