I have a cruise departing in October from Seattle Smith Cove Cruise Terminal at Pier 91 on Holland America.
Have booked the Hampton Inn Seattle Downtown up near the Space Needle. It's located on the right side of the city, yet is close enough to be able to get into town on the monorail. No doubt like other Hampton Inns, the breakfast will be quite junky but at $270/night all in for the three nights I'm there, it'll be fine.
