Book Online: Not only is it simpler to book online, but because you can book your rental car through a price comparison website, you will get a better price than if you made your reservation on the phone, or even worse, waited until you arrived in Houston to book a rental.

Book Early: By booking in advance, you will get a better price, and have access to a better selection of vehicles. If you know your plans, there’s nothing wrong with booking two months in advance. In fact, it can be a very good idea!

Don’t Return Your Car with an Empty Gas Tank: To avoid paying hefty fuel fees, fill up your rental before returning it to the rental car company.

Bring Your Own GPS: Houston is a big city. To get anywhere, you almost always have to get on a highway. Because there are so many highways, and it’s not uncommon to have to take a few different ones to get somewhere, having a GPS is very helpful. However, because rental car companies can charge $10 to $20 a day for a GPS, if you have your own, bring it so you don’t have to pay to rent one.

Get a Small Car: If you don’t need extra space, rent a small car. Rental car companies charge less for their compacts, so you can save money by renting one.
