It's in Everett, around 30-40 min. from downtown Seattle. It's mainly oriented to access by car; however if you don't have one you probably would benefit from using the Grey Line tour from downtown Seattle - leaves from the Sheraton. http://www.graylineseattle.com/sight...roduct_id/1318

I think you'd be happier staying in central Seattle. There are a couple of hotels close to the Boeing plant, but they're comparatively difficult to access without a car. One nice one is the Silver Cloud Inn at Mukilteo - http://scinns.com/12home.htm - built over the water next to the ferry terminal, and they have a shuttle to the Boeing plant. There are buses (nuisance connections) from the ferry terminal to Seattle.

While in the area you really should also visit the Museum of Flight at Boeing Field in south Seattle. http://www.museumofflight.org/

Starbucks tours - not that I know of, but the original Starbucks is in the Pike Place Market.
