We are on the Jun 22 Azamara Adriatic Wonders cruise to Piraeus, Athens that arrives at 5:00AM on Jul 31. How much time does it take to disembark? We have a 7:55AM flight from ATH to Mykonos and will book a private taxi ahead of time. Is this enough time? We have refundable business class tickets, and the next flight is at 1045AM. Thanks in advance.
