Thanks Mike and Kathy! It was a very nice time in a very nice city. Your planning and checking things out made it a enjoyable DO.
I just got home. Metro wasn't on strike the day I left Athens, my passport wasn't really lost just forgot it was in a travel pouch around my neck, ATH-FRA delayed 3 hours, so I got to see the Aegean Lounge after the LH lounge closed. I had a Sheraton Points & Cash layover booked at FRA, $60 USD for which they gave me 32 Euro in a breakfast voucher and free internet. FRA-IAD upgrade cleared,flight left more or less on time at 11 am Monday, as did IAD-SAN. It was like traveling in a protective bubble where nothing could go wrong. I wish everyone could be so lucky, especially all those still stuck in airports everywhere.
