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

  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 extra space, a convertible for summer adventures, or an economical car for budget-friendly travel, utilize the filters on Expedia to help you discover the perfect fit for your journey.
  2. Book in advance to help lower costs: Rental rates can vary based on demand, so it’s wise to reserve your vehicle well ahead of your trip. By booking early, you’re more likely to secure lower prices and have better options, especially during peak travel seasons.
  3. Consider a smaller car for savings: Compact cars tend to be more affordable to rent and easier to park in crowded areas. Mid-size vehicles strike a good balance between cost, 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 not be accessible. This can also apply to renters over the age of 70. Always verify the age restrictions prior to booking.
  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 advantageous option. Other options may include full-to-empty or prepaid fueling, which is also acceptable—just remember to return the vehicle empty in that case.
  6. Save on city and airport pickups: There’s often an additional fee for picking up your rental car at airports, but the convenience may justify the cost.
  7. Know your payment options: Many car rental companies exclusively accept credit cards for payment.
  8. Understand your insurance coverage: Car rental insurance can help you avoid unexpected expenses and provides peace of mind in case something unforeseen occurs during your trip. Adding car rental insurance when booking with Expedia is a straightforward process.
  9. Consider unlimited mileage: If you plan to embark on long road trips, seek out rentals that offer unlimited mileage to prevent incurring extra charges.
  10. Bring your driver's license and ID: A valid driver's license is necessary to rent a vehicle.

Can I drive in Portmarnock with my current driver's license?
If you don't hold a driver's license issued in Ireland, then you'll likely need to acquire an International Driving Permit (IDP) in your home country to be able to rent a car. Also consider that if an IDP is required, it has no validity on its own. You'll be asked to show your driver's license from your home country your passport and other forms of ID as well. Lastly, make sure the credit card used to book the rental matches the name on your driver's license and passport. Some additional requirements for international car rentals are:
  • Age restrictions: You need to be at least 25 in most places to rent a car. If you're younger, it may still be possible to rent a car but you'll have to pay a Young Driver's Surcharge. Additional restrictions may also apply to the types of cars you can rent.
  • Driving limitations: Make sure you read the rules and regulations before you drive away. You typically can't cross country borders, drive on ferries or off road with a rental vehicle.
