The early bird gets the worm. If you agree with that, take the time, today, to reserve your ticket for the ferry ride from Port Angeles to Victoria and back. It ain't cheap but unless your mini is amphibious, you'll need to dig deep for the $150 round trip fare. I have reservations for the 1245 sailing on Monday 6/29 from Port Angeles and the 1030 sailing on Friday 7/3 from Victoria. Black Ball Ferry Line takes reservations on line and requires arrival at the terminal one hour ahead of scheduled departure in Port Angeles, 90 minutes for Customs processing in Victoria. I also booked a room in Port Angeles for Sunday night.
Edit: Added '90 minutes for Customs processing in Victoria.'
