Most rental car agencies in Texas require drivers to be at least 21 years old in order to rent a car. If you are between 21-24, there will be a “young driver” surcharge added to your fee. Some rental agencies also limit the type or size of the vehicle young drivers can rent, so be sure to check pricing and restrictions when you book.
San Antonio is a sprawling city of 1.5 million people, and the best way to see everything it has to offer is to have a car at your disposal. In the mood for amusement park fun? Check out SeaWorld or Six Flags. Take in some culture downtown at ArtPace or the Yanaguana Garden. Of course, no trip to San Antonio is complete without a visit to the Alamo.
The major San Antonio highways are in a wagon wheel pattern, with I-410 and Hwy. 1604 forming loops around the city, and highways U.S. 90, U.S. 87, U.S. 281, I-35, I-10, and I-37 acting as the spokes. Frontage roads run parallel to the highways and make great alternatives during rush hour, with convenient turnarounds if you need to go the opposite direction. The frontage roads do tend to flood during rainstorms, so keep your eye on the weather and plan accordingly!
