We have 4 days to Greece planned and 4 unplanned. We're traveling soon to Athens and then to Santorini. From Santorini, with 4 days left on the ground, what is the most enjoyable way to spend the other four days? We're traveling with our grown teenaged sons.
We could go to Crete for two days and one day trip from Athens to Delphi and one to Nafplio - OR we could go one day to Naxos and then to Nafplio and surrounding areas. What do you recommend?
