Seattle has a comprehensive public transportation system that includes buses, trains, and ferries. As a tourist, it is highly recommended that you buy an ORCA Card which can cover your transportation needs on different modes of transportation. The transportation from one place to another varies in cost estimation but the ORCA Card can save you money.
If you have more time, you can also visit some of Seattle's other famous attractions such as the Seattle Art Museum, the Museum of Pop Culture, and the Chihuly Garden and Glass. For those who have less time, you can skip the bar and focus on visiting other sites like the Museum of Flight, Pioneer Square, and the Seattle Aquarium.
