Advice for Amtrak to Sea-Tac

[tarheeltreehugger]

Hey, I'm planning on riding from the Seattle Amtrak station in downtown Seattle to Sea-Tac (gotta take my boards). I found some great info, including a map and written directions, at the Seattle city website (http://www.seattle.gov/transportation/bikemaps.htm), but wanted to see if anyone had any experience or advice re: this route. Many thanks in advance!
