We're travelling to Santorini in early May 2013. Due to the airlines unexpectedly changing our flights, we now have a longer layover in Athens, arriving at 3am on a Sunday and leaving at 6pm later that day.
We figured we'd tough it out and go without getting a hotel room for the ~3 hours we could sleep. Looking for any suggestions on things to do! What time does the city typically start to wake up (since we'll be arriving so early)? Thanks!
