What are the protocols for after-hours vehicle returns and key drop-box locations at the SeaTac Rental Car Facility?

When returning your rental vehicle after hours at the SeaTac Rental Car Facility, specific protocols must be followed to ensure your vehicle is properly checked in and you avoid additional fees. Upon arriving at the facility located at 3150 South 160th Street, drive up the ramp to the 4th or 5th floor of the parking garage, as these levels are specifically designated for rental car returns. Make sure to park in a well-lit area and lock the vehicle securely. Before exiting the car, gather all personal belongings and remove any trash. Note your exact parking spot number and the time of return, as you will need to document this on the key drop envelope. After parking, take the elevator or stairs down to the ground floor (Level 1) where the rental counters are located. Each rental company has a clearly marked overnight key drop box situated directly adjacent to their respective counters. Place your keys inside the provided envelope, fill out the required information including the exact return time, and drop it into the secure slot. Your vehicle will be officially checked in by staff the following morning when the facility reopens at 6:00 AM. If you fail to document the correct return time, you may be charged for an extra day of rental.
