Booking ferry from Naxos to Athens next June
 

I'm trying to book a ferry from Naxos to Athens on June 13th. It's early to book I know but I have a return flight to Montreal the next day so I thought I should book in advance if possible. I have spent the last couple of hours trying to do this with no sucess! Blue Stars Ferries online reservations system doesn't work well. Any suggestions? I also want to take the ferry from Santorini to Naxos on June 8th and if you can help with this, I would be very grateful.

I don't think Greek ferries' bookings are that far ahead. AND I really don't think you will have any problem getting on the ferries you mention in June. I have often floated around the Aegean at that time and have never needed to reserve ahead.
Brotherlee will probably reassure you further.

Thanks gertie, that's what I suspected. I need to relax!

Just buy your ticket when you're in Naxos. There should be a choice of several sailings. Even in winter, there is a choice of ships to Naxos; today, for example, Blue Star Ferries have two Pireas-Naxos services and GA Ferries has one.
You are travelling from Naxos on a Friday. Generally ferries to the islands are busiest on Fridays and ferries to the mainland are busiest on Sundays - Greek people go for weekends on the islands, and islanders who work or study on the mainland go back to their families at weekends.
Similarly, for Santorini-Naxos, just buy the ticket in Santorini.

Thanks Geoff, that's what I'll do.
