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

  1. Use filters to find the right car: Refine your search by selecting vehicle types and features. Whether you're in need of an SUV for additional space, a convertible for those sunny days, or an economy car to keep costs down, utilize the filters on Expedia to help you discover the perfect 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 car well ahead of your trip. By booking in advance, you’re likely to obtain lower rates and enjoy a wider selection, especially during peak travel seasons.
  3. Consider a smaller car for savings: Smaller cars typically come at a lower rental price and are easier to maneuver and park in busy areas. Mid-size vehicles strike a solid balance between affordability, comfort, and fuel efficiency.
  4. Age guidelines: Drivers under 30 years old may encounter higher deposits or daily charges, and certain vehicle categories—like SUVs or premium models—might not be available. This can also apply to renters over 70. Always verify the age requirements prior to booking.
  5. Check fuel policies: Some rental companies require a full-to-full fuel policy, which means you must return the vehicle with a full tank to avoid additional fees. This is generally the most beneficial option. Others may offer full-to-empty or prepaid fueling alternatives, which are acceptable as well—just ensure you return the car empty in that case.
  6. Save on city and airport pickups: Picking up your rental car at airports often incurs a surcharge, but it may be worthwhile for the added convenience.
  7. Know your payment options: Most car rental companies primarily accept credit cards for payment.
  8. Understand your insurance coverage: Car rental insurance can help you avoid unexpected expenses and provide peace of mind in case something unforeseen occurs during your travels. Adding car rental insurance while booking through Expedia is a straightforward process.
  9. Consider unlimited mileage: If you're planning extended road trips, look for 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 car.

Where can I find a Mercer Island car rental if I am younger than 25?
If you're a young driver looking to rent a car in Mercer Island, it'd be wise to check the terms and conditions of the various car rental companies you're interested in. Some may rent to drivers under 25, some may not. There may be extra costs if you're aged between 21 and 24. To escape any surprise fees and charges on pickup, make sure you know if any extra charges apply to you.
What insurance should I choose for my car rental in Mercer Island?
A thorough insurance plan is a smart idea for your Mercer Island trip. That's why we recommend purchasing collision protection while reserving your rental car with Expedia. This covers your vehicle from theft, accident damage and vandalism. Some destinations may need you to have a minimum level of liability insurance. It's possible that this is included in your rental price or your personal auto insurance, so check what you're covered for and whether you need it.
