10 tips to save on your car rental in and around Harbor Island

1. Use filters to find the right car: Refine your search by selecting vehicle types and features. Whether you're looking for an SUV for added space, a convertible for summer drives, or an economy car for budget-friendliness, utilize the filters on Expedia to discover the perfect fit for your journey.
2. Book in advance to help lower costs: Rental prices can vary based on demand, so it's advisable to secure your car well before your trip. By booking early, you are more likely to find lower rates and enjoy better availability, particularly during peak travel seasons.
3. Consider a smaller car for savings: Compact cars are typically more affordable to rent and easier to park in crowded areas. Mid-size options strike a good balance between price, comfort, and fuel efficiency.
4. Age guidelines: Drivers under 30 may encounter higher deposits or daily fees, and certain vehicle categories—such as SUVs or luxury models—might be restricted. This can also apply to renters over 70 years old. Always verify age requirements before making a reservation.
5. Check fuel policies: Some rental agreements stipulate a full-to-full fuel policy, meaning you must return the car with a full tank to avoid extra charges. This is usually the most favorable option. Other policies might offer full-to-empty or prepaid fueling options, which are acceptable as well; just ensure the car is returned empty in this scenario.
6. Save on city and airport pickups: Picking up your rental car at airports often incurs a surcharge, but the added convenience may justify the extra cost.
7. Know your payment options: Many car rental companies exclusively accept credit cards for payment.
8. Understand your insurance coverage: Rental car insurance can help you avoid unexpected expenses and provides peace of mind if unforeseen events occur during your trip. It's simple to add rental car insurance when booking through Expedia.
9. Consider unlimited mileage: If you plan on taking long road trips, seek rentals that offer unlimited mileage to prevent additional charges.
10. Bring your driver's license and ID: A valid driver's license is essential for renting a car.
