Arriving from the USA
From West coast destinations you can travel to Portland via Amtrak. Most delegates will fly in to Portland International Airport (PDX). From there you can either take a cab (Approximately $45) or the Max light railway ($2.50). This latter form of transport is therefore most economical, and will drop you less than a quarter of a mile from the conference hotel.
