This was my first cruise and I went as a solo.
I got to Seattle a couple of days early to enjoy the city and not be rushed for the cruise. I took the Grayline Airporter to my hotel, the Warwick, and it worked out very nicely. On the Saturday the ship left, I checked out at noon and there was no trouble getting a cab to the terminal. It cost a little over $10 plus tip.
Embarkment took no time, checked my bags, went to the counter, and was heading up the gangway in minutes. Had lunch in the Vista Dining Room, they had a small selection but it was nice to just sit and take it all in.
Great size room, lots of storage and closet space, jacuzzi tub a nice treat, balcony was essential for this trip and it was great to also have a window to gaze out of when in bed.
