we too are using quick shuttle. they are right at the airport and drop you off at your hotel in vancouver. then when you get off the ship they are at the dock to take you back to seattle airport or a couple hotels in seattle. the cost was just $130 total for the two of us. and that is a roundtrip ride. here is there site. www.quickshuttle.com
. check them out. we wont have any taxi's to worry about either. i hope this helps. i prefer to stay in vancouver because it is such a wonderful city and i love to spend time there.
