What are the after-hours return procedures and drop-box locations for Enterprise at the SeaTac Rental Car Facility?

When returning your Enterprise rental vehicle after operating hours at the SeaTac Rental Car Facility, please follow these detailed step-by-step instructions for a seamless experience. First, drive to the SeaTac Rental Car Facility located at 3150 S 160th Street, SeaTac, WA 98188. Approach the parking garage and follow the prominent signs directing you to the Enterprise returns. Take the ramp up to the 3rd floor, which is the designated level for all Enterprise rental returns. Once on the 3rd floor, drive slowly and look for the specifically marked Enterprise return spaces. Park your vehicle in any available spot within this designated zone. Ensure you gather all your personal belongings and remove any toll transponders or rental agreement documents from the vehicle. Lock the car doors and securely close all windows. Next, proceed to the Enterprise rental counter area on the same 3rd floor. Even though the counters are closed after hours, the lighting in this area remains on for safety. You will find a secure, metallic key drop-box mounted on the wall directly adjacent to the counter entrance. Simply drop your keys into the slot of this drop-box. Please note that any returns processed after 11:30 PM will be officially logged on the following business day. Make sure to retain your physical or digital receipt of the rental agreement, as it contains your exact return date and time. If you require an after-hours return receipt, you must request one via the Enterprise website or mobile app within 24 hours of your return.
