Driving in rush hour was faster than waiting for the ferry. We rarely took the Seattle to Bremerton route. But, depending on timing, the Bremerton to Seattle made sense sometimes. Especially since driving required a toll for the bridge.

The ferry system make more sense going to south Whidbey.

You can't use one pass for three vehicles. And to be perfectly clear, you can only use one pass for one vehicle at a time.

Looks like 30 days to me. They can only take 60 if you don't have state ID.
