I am thinking about a family trip (parents and 2 teenagers) to Greece this upcoming Christmas to New Years and am not sure it is a great idea or if there are things which I should be wary. We want a full day or 2 in Athens to see the Acropolis and the other ruins. My wife wants to go to Santorini. I want to go to Crete.

* I understand that this is the low season but am concerned that there will be enough tourist infrastructure to get around and have places to stay. I also wonder if the holiday weeks will make this even worse. We are mainly interested in the ruins and archeological museums. Will these be open at this time of year ?

* I also understand that ferries are not as reliable in the low season so I am thinking that flying between Athens and Crete and Santorini would be a good idea as opposed to a long ferry ride. Does this make sense ? However will there be reliable ferries between Santorini and Crete ?

Any advice or experiences would be appreciated.
