If I wasn't stuck at work today I would be more then happy to give people a lift. There is a starbucks near the terminal exit that would be a good meet up spot though. Also a number of bars in the airport if you feel like you need a mimosa or bloody marry to start the day haha. The light rail is super easy, you just have to know what stop to get off at. They have a website (
www.trimet.org) where you can put in your start location and end location and it will give you the best public transit option on how to get there. You could also ask someone Portland is full of friendly people who are more then happy to direct people new to the city. Hope this helps and good luck haha.
