EMBARKATION:
Seattle airport wasn't very crowded. We didn't see any taxis at the curb, so we called Executive Towncar service (I had called to reserve one a week before. The guy told us to call him when we arrive) and the driver picked us up within 5 minutes of us calling him. It was $35+tip. The trip took less than 10 minutes (I think the driver took a shortcut). We were at Pier 30 by 10:30am. People were arriving already.
We had Platinum check-in. We sat at a row of chairs nearby while husband checked in.
