Where in the world?

To celebrate our graduations and our three-year anniversary (July 6), we went to Greece for a week. After a 3:30am arrival at our hotel in Athens, we still managed to squeeze in a morning visit to the acropolis. Hot, old, stunning. We debated on which was better: seeing only the "real" old stuff, or seeing the rebuilt buildings as they used to be, albeit made of "fakes". Opinions?
