What are the procedures for returning rental vehicles outside of standard operating hours at SeaTac Rental Car Facility, and how do key drop box locations impact final receipt generation?

At the SeaTac Rental Car Facility, customers can return their rental vehicles outside of standard operating hours (Monday to Friday, 8:00 AM to 6:00 PM, and Saturday to Sunday, 8:00 AM to 5:00 PM) by utilizing the designated key drop boxes located at specific rental car company lots. For example, Alamo, Avis, and Budget have their key drop boxes situated at 18200 International Blvd, while Enterprise and National have theirs at 17801 International Blvd. The keys are to be deposited into these boxes, and the vehicles are inspected later by the rental car staff. The final receipt is generated after the inspection, taking into account the condition of the vehicle and any additional charges incurred. The process typically takes 24 to 48 hours. As of 2022, a late return fee of $20 per day is applied if the vehicle is not returned within the agreed-upon timeframe. The exact waiting times and fees may vary depending on the rental car company and the terms of the rental agreement.
