We went on this tour with the Citypass that we purchased for our Seattle trip. The pass comes with a 1 hour harbor cruise or you can upgrade for around $15-$20 dollars to the 2 hour locks cruise. For our trip, they bussed us to where the ship was docked and we boarded. They had lots of seats up on deck for you to sit on and some inside if it got too cold. The coolest thing was going through the locks. It was interesting to see how that all works. It was also cool being in the Harbor and seeing the city from the water. The ships crew were incredibly nice and full of information. They had light snacks and drinks on board for you to purchase and they also had a bathroom. I would definitely recommend this cruise to anyone.
