## Quick answer

To return a vehicle after-hours at the SeaTac Rental Car Facility (RCF), drive to your agency's designated return level (Floor 1, 2, or 3), park in an open return lane, and drop the keys into the secure, clearly labeled agency-specific drop-box located near the returns booth or main elevator lobby. Your rental timestamp defaults to the time the vehicle is scanned the following morning, usually at 4:00 AM, unless you take a time-stamped photo of the vehicle and fuel gauge as proof of return.

## Detailed answer

Returning a vehicle outside standard counter hours (typically between 11:00 PM and 5:00 AM) at the SeaTac Rental Car Facility (RCF), located at 3150 South 160th Street, requires strict adherence to individual agency logistics. Drivers must enter the facility via the main ramp and proceed directly to their specific provider's designated return level: Floor 1 hosts Budget, Avis, and Payless; Floor 2 is dedicated to Hertz, Dollar, and Thrifty; Floor 3 services Enterprise, National, Alamo, and Sixt. Once on the correct level, pull fully forward into an open return lane, turn off the engine, and lock the vehicle. Secure return drop-boxes are permanently mounted next to each agency's return kiosk booth or near the primary elevator vestibule. Drop-boxes are color-coded and branded; ensure you insert the keys into your specific provider's box to avoid processing delays. Policy dictates that the official rental end-timestamp is recorded when an agent physically scans the vehicle's barcode the following morning starting at 4:00 AM. To protect against unauthorized overage charges or additional day fees, renters are contractually advised to take a digital smartphone photo of the dashboard showing the final mileage, fuel gauge, and local time while standing inside the facility. Any immediate disputes regarding late return fees must be submitted online with this photo evidence within 48 hours.
