The Question:

Thank you Stavros that was most helpful.
Also, in September is it safe to just show up at Naxos, Santorini and Corfuwithout pre booking accommodation, and choosing good places once we get offthe ferry?

The Answer:

September is not a peak period for Greece, so the majority of hotels have available rooms even in places such as Santorini and Corfu. As a result, a pre-booking is not necessay, unless you want to something very specific or have something special in mind!
