Seattle -> Portland Trains Canceled – what now?

I was supposed to be taking the amtrack from Seattle to Portland this Friday, the 14th. Unfortunately, my ticket was canceled due to a warehouse fire and there are no standard bus tickets available. I have to be there before 2pm.

How am I to get from Seattle to Portland now? A rental car or flix bus are $120+.

Any advice appreciated! Is there maybe a rideshare group?

UPDATE I called Amtrack, and they were able to help me out and get me a bus for only $20!! The website wasn’t showing this.
