Thinking about 14 nights in Greece - ideally in May or September.
Arrive in Athens, stay 3 nights;
Rent a car for drive to Monemvasia, stay 3 nights (maybe drive to Mani peninsula one day);
Drive north to Nafplio (by way of Mystas for mid-day visit), stay 3 nights (see Mycenae and Epidaurus);
Drive north and west to Delphi, stay 3 nights;
Drive to Vouliagmeni for final decompression, stay 2 nights, leaving for the airport early on the last day.
We don't get the islands, but will save them for another trip. This is an early first stab. I realize there's a bit of backtracking, but without taking long, long drives through the west Peloponnese, I don't see a way to avoid them. Can shake it up by stopping at different places going south and then north.
