Walk from the ship to the port gates (5 mins) pick up the red hop on hop off bust which takes you round all the important bits of Athens for just 22 Euros, The buses have Air Con , an open top deck and are great value for money. The Red bus lin has more buses than the yellow one
Full of life and very interesting
Very pretty and photogenic, not really much to do outside of Mykonos town . Tours not really worth it
