We took the tour at the end of the cruise that showed us the sights of Seattle and left us at the airport. It made sense as we could do this instead of a transfer and I'm glad we did. That said, the Space Needle and Pike Street were extremely crowded and it was impossible to see much. However, the bus driver was knowledgeable and fun. He highlighted many places in town beyond the scheduled stops and we enjoyed ourselves.
