I have been to Sifnos a number of times and want to get my ferry tickets ahead of my trip as I want to make sure that I get theferry crossing. When I go on the official Greek ferry website, it tells me that I can oly get tickets for VIP class which are about three times the price of the economy tickets. I know that there is so much room in economy and cannot believe that it is fully booked already (we are traveling in mid June).
Does anyonw know of another way of getting ferry tickets? Is there an agency I can call (I live in London) or is there an alternative website?
