I was browsing around today and I noticed first that the Keystone – Port Townsend will be running a passenger only service for January while the one vessel goes in for a refit. Back in February, the schedule is “until changed”.
Reservations can be made (free of charge) no more than 1 month in advance and must be picked up at least 45 minutes prior to sailing (but not more than 90 minutes).
This won’t affect getting there, but returning (if you plan the farewell luncheon) means that you’ll have to get the 4pm ferry as the 3 will be too early to get there 45min ahead (unless, of course, you can go home en femme).
