Frequently asked questions

What happens if I need to cancel my King County car reservation?
We’ve got good news! You should be eligible for a complete refund if you advise us a minimum of six hours before pickup. Your itinerary contains details about this, and so does our Customer Service Portal. Not all prepaid rentals result in a refund though, so you may want to go over the rental agreement.
How do I find the best car rental deals in King County with Expedia?
Expedia makes it a breeze to compare costs, offers and providers, and to check customer recommendations. Combine your King County car rental with hotel or flight bookings and you’ll make even bigger savings.
How old do you have to be to rent a car in King County?
Generally, the requirement is 21 years and over in King County. You should be aware that most outlets will charge additional fees for young renters. Check before you sign up, as different rules may apply between rental car suppliers. Bear in mind that if you’re planning to rent a luxury ride or a large car like an SUV, you may need to be older than 21.
What do you need to rent a car in King County?
The main requirements are your driver’s license and a credit card in the same name. Car rental companies will offer you insurance, which is optional. But you may have to provide proof of other coverage if you opt out. Be sure to check your policy requirements to avoid any issues.
Can I rent a car for a month or longer in King County?
Yes. We partner with quality suppliers that offer weekly and monthly rentals for all types of cars. Pick up one of our long-term car rental deals and explore every inch of King County — or beyond!
Where can I find a King County car rental if I am younger than 25?
If you’re a young driver looking to rent a car in King County, you’ll need to check the policies of the various rental companies you’re interested in. Some may rent to drivers under the age of 25, some may not. There may be extra fees if you’re aged between 21 and 24. To escape any surprise fees and charges at the rental counter, make sure you do your research.
