We are planning on visiting Hydra for 2 nights on our trip to Greece. We are landing at the airport at 2:00 PM Aug 4, 2010 and are thinking on taking the express bus to Piraeus Port. Should take about 1-1/2. Here's where's I'm running into a problem. I can't seem to find any ferry schedules that far out, which is understandable, so I don't know if scheduling will be a problem. I've visited the Hellenic Seaways website and it appears that the last ferry they offer is at 5:00 PM. If my flight is a bit delayed, or I can't find the ticket agent office to pick up my reserved tickets quickly, am I running it too tight. I keep reading that there are numerous ferries to Hydra, but am having trouble finding anything online. What's the most efficient way of doing this? Does anyone know what the earliest I can reserve a ferry?
