Thank you to all for the suggestions. I think I will just hang out in the airport.
One other question - I am connecting from a different airline on a different PNR in Seattle. I have a choice - 5 hours in Seattle or 1.5 hours in seattle. I would prefer to do the 1.5 hour connection. Will I get a boarding pass so that I can just walk through the airport in seattle and get on the EVA flight?
