We have just arrived to Seattle, staying in the Pioneer Square BW. As always we were ble to check-in early (11AM), got free upgrade.
Boxo, if you are here, have fun:-) It is cold, rainy, but I hope you wil enjoy every minutes of your stay.
Check the "First Starbucks", have a piroshky, or get in line for chowder at Pike Street Market. if you are over 40 you might enjoy the Museum of Pop Culture.
Probably it is late to mention, but the Boeing tour is excellent. (They would pick up you at the hotel.)
I hope you come back to share YOUR experience.
