We will take the ferry to Naxos on 30 June and back on 2 September. Would you recommend us to buy the Retourn ticket at one time or would you buy it separately? And also what is the right price? I found on http://greeceferries.com/ one route for 33,50 E but on http://www.go-ferry.com/ I had to choose the type of the accommodation, so I chose the Economic one (I really want the cheapest one) and the price is 60 E and it's the same company Blue Star. Do you know anything about that?
