Yes, I know, the minutia that keeps an obsessive compulsive travel planner awake at night! But here goes...

Does anyone know the max amount that one can withdraw from whatever ATMs are available when arriving internationally at PEK? If there are several machines, is one bank better than another?

And given that, as I'm not familiar with the currency, is there a suggested "off amount" I should request so that I'll get at least some smaller denominations?

Thanks
