10 tips to save on your car rental in and around Castleknock

1. Use filters to find the right car: Refine your search by selecting vehicle type and features. Whether you require an SUV for extra space, a convertible for summer fun, or an economy car for budget-friendly travel, utilize the filters on Expedia to discover the best option 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 ahead of your travel date. By booking in advance, you are more likely to obtain lower rates and enjoy greater availability, especially during peak seasons.
3. Consider a smaller car for savings: Generally, smaller cars are less expensive to rent and easier to maneuver in crowded areas. Mid-size cars strike a good balance between affordability, comfort, and fuel efficiency.
4. Age guidelines: Drivers under the age of 30 may encounter higher deposits or daily fees, and certain vehicle categories—such as SUVs or luxury models—might not be accessible. This can also apply to renters over 70 years old. Always verify the age requirements before making a reservation.
5. Check fuel policies: Some rental agreements require a full-to-full fuel policy, meaning you must return the car with a full tank to avoid additional fees. This is typically the most favorable option. Other policies may offer full-to-empty or prepaid fueling options, which are acceptable as well. Just make sure to return the car empty in that scenario.
6. Save on city and airport pickups: Picking up your rental car at airports often incurs a surcharge, but the added convenience may make it worthwhile.
7. Know your payment options: Many car rental companies only accept credit cards for payment.
8. Understand your insurance coverage: Car rental insurance can help you avoid unnecessary expenses and provides peace of mind in case something unexpected occurs during your trip. It's simple to add car rental insurance when you book through Expedia.
9. Consider unlimited mileage: If you're planning long road trips, seek out rentals that offer unlimited mileage to prevent additional charges.
10. Bring your driver's license and ID: A valid driver's license is necessary to rent a car.
