What is the floor-by-floor layout of the SeaTac Rental Car Facility, and where are the SIXT counter, vehicle pickup, and return areas located?

The SeaTac Rental Car Facility, located at 3150 S 160th Street, is a massive 5-story structure designed to streamline the rental process for travelers arriving at Seattle-Tacoma International Airport. The layout is intuitively segmented by function across its 5 levels to minimize confusion and foot traffic. Upon arriving via the dedicated blue shuttle buses, which take approximately 8 minutes from the main terminal, customers will navigate the building vertically. Level 5 houses all the rental counters. Specifically, the SIXT counter is strategically positioned on the far right side of Level 5, immediately recognizable by the striking kinetic art installations that feature moving metallic sculptures. Once the rental agreement is finalized on Level 5, customers proceed down one level to Level 4 for vehicle pickup. Level 4 is a vast parking garage area where the SIXT fleet is parked in designated numbered spaces; you simply match the space number printed on your rental contract to locate your specific vehicle. When your rental period concludes, vehicle returns are processed on Level 3. You will follow the clearly marked overhead signs for returns as you drive into the facility, pulling into the designated SIXT return bays on Level 3 where attendants will inspect the vehicle and process your final receipt. Levels 1 and 2 are primarily utilized for employee parking, fleet management, and vehicle washing and maintenance, ensuring that the customer-facing levels remain uncluttered and efficient.
