I am visiting Greece with my husband and couple of friends end of march.
Me and my husband will reach 2 days earlier than our friends.
We want to do Delphi and Peloponnese in these two days.
We land Athens march 26 early morning 6:00 am
We can rent a car/taxi and drive to Peloponnese, spend night in Corinth.
day 2 we drive to Delphi from Corinth spend day in Delphi and return to Athens in the late evening.
Please let me know if this sounds doable.
