What are the level-by-level lane designations for returning specific car brands at the SeaTac Rental Car Facility, and what are the after-hours key drop-off procedures?

The SeaTac Consolidated Rental Car Facility features 4 distinct parking levels specifically designated for different rental brands to streamline the return process. Level 1 is exclusively designated for Alamo, National, and Enterprise returns. Level 2 accommodates Avis and Budget vehicles. Level 3 is strictly reserved for Hertz and Dollar returns. Finally, Level 4 handles Thrifty and Fox Rent A Car vehicles. Clear overhead signage and color-coded lane markers guide drivers to the appropriate parking bays upon entering the facility. For after-hours returns when the customer service counters are unstaffed between 12:00 AM and 5:00 AM, customers must park the vehicle in the designated brand-specific lane, remove all personal belongings, and lock the car. The after-hours key drop-off procedure requires placing the keys and the completed rental agreement into the securely mounted lockboxes situated at the ground-level customer service podiums. Each lockbox is clearly labeled with the corresponding rental company logo and features a one-way deposit slot to ensure key security. Renters should verify that the vehicle's mileage is accurately recorded on the contract before dropping it in the designated slot, as no personnel are available to perform exit inspections during these hours.
