GMan,
Pt. Angeles to Vancouver by car around the long way will take you the better part of a day. It would almost be faster and cheaper to take the ferry to Victoria, then the ferry to Vancouver.
You could do the walk-on in Pt. Angeles, walk two blocks to the bus station and go downtown to downtown. It's a nice, comfortable, trip.

As far as getting from Seattle to Vancouver. It is possible I will be available to take two or three. I may have a show south of Seattle and will be returning to Vcitoria via the Gathering. I'll keep you posted.
