Athens

Athens is not a city I would visit again, though having said that, I'm glad I had the opportunity to visit it once.  We went to The National Archaeological Museum.  WOW!  What a fantastic collection they have.  We of course went to see the Parthenon and the Acropolis.  Overall though, Athens felt like a normal, big, dirty city.  Great for the historic sites, but otherwise, I'd skip it.
