Thanks to some of the well traveled people who participate here, I've already booked 1 night at Attalos Hotel at the end of August. We arrive in mid morning, and will be starting our cruise the following day, which departs at 4PM. I know that we will arrive pretty tired, and will probably have to get a couple hours of sleep. What makes the most sense in spending a nice day in Athens? We want to have a busy, well balanced itinerary, but not overwhelming. We want to experience a major attraction, I guess Acropolis. Other places of interest are central markets, Parthenon, agora, plaka, syntagma square. Should we walk everywhere? We also want to do some shopping, experience the genuine, no nonsense but delicious cuisine, and get a feel for this incredible city. I hope to use a bit of everyone's input to plan an unforgettable day, and make us want to return. I'm so grateful for all of the kind folks who take the time to share their knowledge in this forum.
