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

  1. Use filters to find the right car: Refine your search by selecting the vehicle type and features that suit your needs. Whether you require an SUV for additional space, a convertible for sunny days, or an economical car for budget-friendliness, utilise the filters on Expedia to help you discover the ideal vehicle 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 vehicle well ahead of your trip. By booking in advance, you’re more likely to obtain lower rates and greater availability, particularly during peak seasons.
  3. Consider a smaller car for savings: Smaller vehicles are typically more affordable to rent and easier to park in crowded areas. Mid-size rentals strike a good balance between cost, comfort, and fuel efficiency.
  4. Age guidelines: Drivers under the age of 30 may encounter higher deposits or daily surcharges, and specific vehicle types—such as SUVs or luxury models—may not be available. 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 stipulate a full-to-full fuel policy, meaning you must return the vehicle with a full tank to avoid additional charges. This is generally the most advantageous option. Others may provide full-to-empty or prepaid fuel options, which are acceptable as well. Just ensure you return the car empty in this case.
  6. Save on city and airport pickups: There is often a surcharge for collecting your rental car at airports, but the added convenience might justify the extra cost.
  7. Know your payment options: Many car hire companies only accept credit cards for payment.
  8. Understand your insurance coverage: Car hire insurance can safeguard you against unforeseen expenses and provides peace of mind should anything unexpected arise during your travels. Adding car hire insurance is simple when booking through Expedia.
  9. Consider unlimited mileage: If you’re planning extended road trips, seek rentals that offer unlimited mileage to avoid incurring extra charges.
  10. Bring your driver's license and ID: A valid driver's licence is required to hire a car.
