Trying to figure out what my lounge options are - or more importantly, if I have plenty of time (as in too much time as I wait for a late flight), where I should park myself give the limited lounge options.  I'm flying Qantas out of Shanghai - I am platinum. I don't care how far I have to walk and I will have at least 3 hours in the airport.  What's my best option? Thank you.
