We are going to be travelling to Santorini from Athens on July 6th (a Sunday). I have seen on the various websites re. the ferries that there are a variety of ferries that make that trip. My question is- how far in advance, if at all, is it necessary to book two tickets for a fast ferry to Santorini at that time? Should it be done online from home or could we purchase tickets when we get to Athens a couple of days before we want to travel. The ferry schedules aren't all official yet for July, so I don't want to book too early in case there is a better time that is available later.
Similarly- should Santorini to Naxos and Naxos to Piraeus be booked in advance?
Lastly, do Olympic or Agean Airlines ever drop fares closer to the summer, or add more flights, or is what is posted on their websites now likely to stay the same.
Thanks to anyone who can shed any light on these questions.
