I am trying to make reservations from Metochi to Hydra on the ferry as explained in the Greece and Peloponnese book. I cannot find anything in English. I have even gone on the Facebook page. Does anyone have experience with making these reservations? I believe I have successfully emailed them with this question but I’m not certain they will respond in English. How does one go about this?
There is no reservation for this trip, it's not a ferry, but a daily local boat service. You will pay before boarding (€7.50 / passenger.), there's a booth.

The schedule (in Greek) is available here:
Here's one of the best websites for not only Hydra but how to get there including from Metochi:

Click on the three "lines" on the top left for more info.
Unfortunately it doesn't appear you can make reservations show show up.
