There will be parking space available at the Boss Residence and at the neighboring homes, they are doing us a huge favor, but it is limited.
Arrive at the terminal at least 45 minutes in advance and purchase a ticket to Bainbridge Island. The attendants will direct you to a numbered lane to wait in. When loading, the attendants will direct you to where on the boat to park. If you the ferry fills up and you miss it, then you will automatically be waiting at the front of the line for the next ferry. When the ferry ride is over, you will drive off the boat directly onto Washington State Road WA-305. When returning to Seattle, you will drive off the boat to the intersection of Alaskan Way and Yesler Way.
