I'm planning a work trip to Seattle next month and we will need to get from Bellingham to Bremerton. I was planning on taking the Edmonds to Kingston Ferry, and was curious about how early before the departure time from Edmonds will we need to arrive? We would ideally like to take either the 1240 or 135 ferry out of Edmonds and would value any advice this group has!
