oz,
after a 14 hour flight, I'm game for a 3-mile walk (that's 5 km to you

)
But can you tell me where the observatory is in relation to the harbor bridge, the Opera house, or the Westin on Martin Place? I know the concierge can point me if it comes to that....
Thanks!
And any time is fine with me. I think we were shooting for morning so as to not miss part of the Bowl...
