I also live in Kitsap and I'm curious what privacy issues you ran into? I'd normally try to use John/Jane Doe info for this type of thing but it sounds like they were requiring ID. Were you able to find a workaround?
I looked it up in my email and I also found that later on they switched to requiring a social media (facebook, google, something else?) account in order to reserve a spot on the taxpayer funded, government-run ferry. I actually quoted part of the privacy policy in my (unanswered) email to kitsap transit:
