To ride Seattle to Neah Bay and back in one day is at least 9 hours of road time. Also dependent on ferry schedules( if used enroute.) I don't think that would work for many folks.
Neah Bay is two hours from Port Angeles. I think folks forget that Olympic National Park is bigger than the state of Rhode Island and the Peninsula is much bigger than that. For me to drive (legally) to Pacific Beach is about three hours.
Forks is one hour west of PA.
Port Angeles to the Nick... The better part of 2-3/4 hours. If you hit the ferry just right.
1-1/2 hours road time from my house on the west side of PA to the ferry dock at Kingston.
Then there's hooking up with the ferry which is running about every 45 minutes. With a 30 minute crossing.
From Edmonds on 104 to I-5 and down to the 81 St. turn off is about 20+ minutes. Then, dependent on local traffic, probably 15 minutes to Aurora, south to the 47thSt (??) turnoff to drop down to Fremont and across to the Nick.
A ferry hint for those of you grabbing the Edmonds ferry. Motorcycles need not line up with that long line, waterfront row, of cars and ticket booths. Instead bypass all that hoopla, drive right to the dock (watch out for the train crossing, it is active!!). Park just off to the right of the dock "toll booth" (it isn't a ticket selling booth),walk across the wharf to the ferry terminal and walk in and buy a ticket. If no one is at the inside booth there's a little ticket dispenser/kiosk just inside the door. Go outside, present your ticket to the guy in the booth and motor to the front of the line.
Keep in mind that the ferry ride is windy. Put your tranny in first on the sidestand. Also, because of the wind the engine cools rapidly!! You may need cold start procedure at the other side. (I always get back to the bike well before we dock, prep everything and get it ready to kick when they allow us to "start yer engines"!)
Ferry schedules are available online. Here's the Edmonds/Kingston schedule:
