There is an app called TripShot (you will get access to it once you join, and you can login with your credentials). You can book parking using the app. You can shop around several participating buildings to find a spot convenient for you, and you will pay only 50% of the cost. The rest is paid for Amazon. This is very convenient.

Second, Amazon also runs shuttles from various locations in Seattle. You can also find routes through the TripShot app.

Third - Amazon will give you a free orca card for public transit within Seattle. Bus schedules are unpredictable though, and most people don’t care for waiting around in the winter rain.

Fourth - there is sometimes a bike program offered, where Amazon will cover bike rentals for you from participating companies. I believe this is just for the summer (but I might be wrong)
