Airport Shuttle - Seattle Airport
 

I will be arriving after 10 p.m. on a weeknight and would like to get suggestions for the best way to get into the downtown area (Westin at 5th Avenue). I will be travelling alone, so safety is a major consideration. Thanks ahead of time for your ideas!

I would just take a taxi. You'll arrive too late for the Airporter bus (last one is at 9 PM). Shuttle Express would be another option.

I agree with NW Wanderer, but if you want the shuttle, here is the link: http://www.shuttleexpress.com/airportTransfers.html

Thanks for your help. I'll just take a taxi!

I agree. Just take a taxi. From baggage claim, you walk over the skybridge, into the parking garage. Follow signage to Ground Transportation. That's what I always do traveling solo from SeaTac. There are no safety concerns.
