I'm hoping someone can give us some guidance on which 1-2 islands would be best to visit during 1st week of April 2015 after we complete our RS Athens/Heart of Greece tour. We know it will be too cool for swimming/sunbathing and that's ok, but want to enjoy some quiet time and the beautiful sights of the islands. We are thinking of going to Santorini, Naxos or Mykonos, or perhaps two of the three if our 4-5 nights time frame is reasonable for this goal. We aren't interested in bars/nightlife but do want to enjoy some good restaurants, and soak up the local flavor/culture of the area. From my research it appears that flying from Athens on Aegean to whichever island and then possibly a ferry to the next destination would be best. Flight schedules are out for April now but not sure whether many ferries are traveling at this time.
We are a mother and daugher group in our 40's and early 70's and in pretty good shape, although we'll be ready for some rest after the busy RS tour before the islands.
