I am planning on doing a Portland to Seattle train trip in August for a couple concerts. I would be spending a couple nights in Portland, then taking the Amtrak to Seattle for just one night. So far I've figured out the Portland part of the trip, and am looking for some tips on Seattle. The show is at Showbox at the Market. Any ideas of a place to stay with fairly easy transportation options to the show? I know the area can be expensive, so the cheaper the better. I'm a 23 year old guy so I don't need anything too fancy. Also, I would need to get to the airport the next day. What would be the best way to do this? Thanks for any advice!
