## Detailed answer

The SeaTac Rental Car Facility allows customers to return their rental vehicles outside of standard operating hours. To do so, customers must use the designated Level 1 garage parking areas. Each rental car brand has its own designated key drop box where customers can deposit their vehicle keys. For example, customers renting from brands like Enterprise or Hertz can find their respective key drop boxes near their designated return areas. The facility operates 24/7 for returns, but customers are advised to check with their rental company for specific after-hours return policies. The address for the facility is 18200 International Blvd, SeaTac, WA 98188. Customers can expect a waiting time of up to 30 minutes during peak hours for the return process to be completed. It's recommended to fill up the gas tank before returning the vehicle to avoid a refueling fee, which can range from $10 to $25 depending on the brand and location. Additionally, customers should ensure they return the vehicle in the designated area and follow the instructions provided by their rental company to avoid any additional fees.
