oh. Grand Central FunPass sales are at the currency exchange window at the end of the ticket/service areas.

if you walk in by the Lexington Avenue subway, it's the first window on the left. shallso all else should fail, walk into the Great Hall, walk over to the little glass oubliette, and face the timetable boards. The farthest window to your left is the currency exchange. For what it's worth, they've been open at least as late as 7 in my travels, but i know not the hours.

i dinna about the newsstand; i'm just adding my own experiences here.
