SeaTac

SeaTac is a city in southern King County. Its name is a portmanteau of its larger neighbors: Seattle to the north, and Tacoma to the south.

Understand
Most visitors will only visit SeaTac for the Seattle-Tacoma International Airport, itself nicknamed Sea-Tac – the city named itself for the airport (albeit without the hyphen in the name, a distinction that isn't very widely known). Outside of the airport and its surrounding bevy of related businesses, including the corporate HQ of Alaska Airlines, there's little to attract tourists, although business travelers may appreciate the cluster of hotels close to the airport.

By car
From Interstate 5 (I-5), take Exit 154B (SR-518) for the airport. The same interchange connects to I-405's southern end.

By bus
Some intercity bus routes traveling beyond the region stop at Seattle-Tacoma International Airport, though there far more options in Seattle.

Sleep
There are numerous hotels & motels lined up along International Blvd (Hwy 99) through SeaTac that many travelers find better value in staying in comparison to those in Seattle. Tukwila, immediately to the north and to the east (opposite side of the freeway), also hosts several hotels and offsite airport parking. A number of them do offer free (or for a small fare) shuttle to/from the airport terminal and other nearby places (such as car rental offices):
