I spent about 2 weeks in the Greek Islands, and another couple days in Athens on the way back.  I spent most of the time in the Cyclades - Naxos, Ios, and Santorini - before flying down to Rhodes for the last few days.  (The Cyclades have great ferry connections, but the connections between them and the Dodecanese are basically nonexistent.)  Eb Keshavarz, my roommate from b-school, and his brother Hossein joined me for the week in Santorini.
