## What to know

The SeaTac Rental Car Facility is located at 17801 International Blvd, SeaTac, WA 98158. After-hours key drop boxes for various rental car agencies are available at this facility. The exact locations vary by agency: Alamo and National use the Level 1 Garage counter area with a designated drop box located 50 feet north of the counter, while Avis and Budget have their drop boxes on the designated rental floor, precisely 200 feet east of the elevators. Enterprise and Hertz use a separate after-hours drop box located outside the facility, near the bus stop on the north side of International Blvd, within a secured box that is accessible 24/7. The drop boxes are available for use between 10 PM and 6 AM on weekdays and 24 hours on weekends. It's essential to return keys and contracts to the correct drop box to avoid a late return fee, which can range from $20 to $50 per day, depending on the agency's policy. For example, Alamo charges a $25 late fee if the vehicle is returned after 11 PM.
