I am going to be booking flights for 6 adults to get from Athens to Santorini and have a question about the timing. My plan is to leave Hydra via boat to Piraeaus, catch a bus to the Athens airport for an afternoon flight. I believe there is a boat that leaves Hydra at 7:05am and arrives at Piraeaus at 8:40. Now we need to catch a connecting bus to the airport and I haven't found a good resource for bus schedules. How often do they depart? Hourly? If I can get on a bus by or before 10:30 that should get us to the airport by noon and thus I am thinking if I can get a 2pm(ish) flight we should be touched down in Santorini by 3pm. Has anyone done this and can you shed any light on any pitfalls I should be aware of?
I had originally planned to get on a ferry but from what I am seeing - they all depart Piraeus in the 7:00am hour and we won't be able to get there any earlier than 8:40. And the one later ferry gets us to Santorini late at night.
Also, if anyone has any good bus schedule resources period - that would be helpful. My entire itinerary is Athens first, then bus to Delphi for a couple nights, then bus to Hydra (Pireaeus) for 3 nights and then catch a flight to Santorini. We will fly back to Athens for 1 night before heading home.
