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 the vehicle type and desired features. Whether you're looking for an SUV for extra space, a convertible for summer drives, or an economy car for budget-friendly travel, utilizing filters on Expedia can help you discover the ideal match for your trip.
  2. Book in advance to help lower costs: Rental prices can vary based on demand, so it's wise to reserve your vehicle well ahead of your travel dates. Booking early typically allows you to secure lower rates and ensures better availability, particularly during peak seasons.
  3. Consider a smaller car for savings: Compact cars are usually less expensive to rent and easier to maneuver 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 charges, and certain vehicle categories—such as 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 agreements require a full-to-full fuel policy, which means you must return the car with a full tank to avoid extra fees. This is generally the most beneficial option. Other policies may include full-to-empty or prepaid fueling options, which are acceptable as well; just make sure to return the car empty in those cases.
  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 primarily accept credit cards for payment.
  8. Understand your insurance coverage: Car rental insurance can help you prevent unexpected expenses and provide peace of mind if anything unforeseen occurs during your trip. It's simple to add car rental insurance when booking through Expedia.
  9. Consider unlimited mileage: If you plan to take long road trips, seek out rentals that offer unlimited mileage to avoid additional charges.
  10. Bring your driver's license and ID: A valid driver's license is necessary to rent a car.

What do you need to rent a car in Mercer Island?
You'll need to present your driver's license and a credit card in your name at the rental counter. Prior to pickup, check with your rental supplier whether other documentation is needed. For example, you may also need to show proof of auto insurance.

Based on prices found over the past seven days, you could've slid into the driver's seat of your own rental car for just $37 a day. The second lowest daily price in Mercer Island was $99.

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.
