It is quite nice with good service. One of the best parts about this stop is its location. It is a short hop to Boeing Field to see the 747's being built.
Tours are available.
The Boeing Museum is first class and worth the trip. McChord AFB down in Tacoma also has a great Museum. The Jet deck has been open here for years, and has a good prices. Best of all is the great view of the sunsets, and the runway. Well worth taking the time to see.
