Flight
The primary airport to fly into Seattle with easy connections via the Lightrail to Downtown Seattle. If you're renting a car, there are also a lot of options near the airport with shuttles.
Travel Note
Ferries are the primary way to get to Bainbridge Island, although there is an option to drive around if you don't want to worry about ferry lines. Otherwise you can take either the Seattle/Bainbridge Ferry or Edmonds/Kingston. I've linked the website below which includes the ferry schedule - just make sure you're looking at it going the correct direction! I estimate about an hour from getting on the ferry to arriving at the venue. It is not uncommon to have to wait for one ferry if you're driving on, so please include buffer time. If you choose to walk on, you'll need to request an uber.
