## Quick answer

To return your vehicle after hours, proceed to the designated Alamo floor, pull forward, and use the key drop box.

## Detailed answer

To return your rental vehicle to the Alamo SeaTac Rental Car Facility after operational hours, follow these steps: First, locate the designated Alamo floor, which is clearly marked. Once you arrive at the designated floor, pull your vehicle forward to the designated area. You will find a key drop box located at the SeaTac Rental Car Facility, 18200 International Blvd, SeaTac, WA 98188. Simply deposit your keys into the key drop box. Please ensure that you have completed the rental return process by filling out the rental agreement and noting any damages or issues with the vehicle. The facility is open 24 hours for drop-offs, but the rental return office is staffed from 6:00 AM to 12:30 AM. If you return your vehicle outside of the staffed hours, you will be processed the next business day. A late return fee may be applied if you return the vehicle after the agreed-upon return time, which is typically calculated at a rate of $30 per hour for the first 4 hours, and $60 per hour thereafter, with a maximum daily rate of $240.
