Hi Dear, How much approximately time is taken to reach from landing place to reach X95 bus? And secondly how much time X95 takes from airport to syntagma. I will shortly go to Athens via Rayan Airline. Same day I will fly from Athens. The time b/w two landing and again departure is 6 hours. During this time, I want to go Sytgma via X95, and just see a glimpse of Acropolis, Temple of Zeus, Olympic Stadium, and Prison of Socrates. And then come back to airport via X95. Is this possible? I don't need to go through immigration and submit any checked luggage. Just I need to pass through security checks.
From airport to bus stand approx. 15 min (use overbridge and avoid underpass) and from bus stand to city centre approx. 45 mins. I am afraid if you can cover these many places within 6 hours time. I think you can see syntagama Square which is famous for change of guard ceremony and Olympic stadium from outside without any tickets. If you buy ticket and want to know in details it would be difficult to cover even one place. Acropolis being on the top will be visible from almost every part in the city center. Please take atleast one hour margin for traffic and other uncertainty.
