Since you list 12 things in 14 days most of your experience in Greece will be looking out through a car window as you speed along. You really need to be more realistic and prune your list. Some tips & observations from 12 lengthy trips to greece:
• research realistically how long it takes to get to one place from another (and don't go by US standards of Interstates & smooth terrain). Use a trip planner In ADVANCE like https://www.viamichelin.com/web/Routes shows best route on a map, Plus detailed instructions AND time + cost (petrol/tolls). Here also a fab online map of peloponnese PLUS mainland edge up to near Delphi - http://euro-map.com/karty-grecii/peloponnes/podrobnaya-turisticheskaya-karta-peloponnesa.jpg PLUS a downloadable Mainland map, showing Meteora & more - http://www.greeka.com/greece-maps/northern-greece-map.htm
• In September sun goes down earlier & you do NOT want to drive in the dark
• Be aware that even tho major sites are supposed to stay open til 5 or 7:30 until November, since the Greece budget crunch many many sites begin closing at 3 pm despite what "official" websites say. Always recheck beforehand
• Have you really LOOKED at a map? If you want to visit the Zagohoria area you will need to skip the last 5 things on your list. A friend of mine visited the Epirus area and it took her 10 days and she' LIVES in Greece and drives in Greece!! Be realistic.. I think you need to skip it if you want the Pelopponnese.
• Mt. Olympus is for climbers -- otherwise it's a view from the coastal highway en rout to Thessaloniki.
• The Marathon area has changed so drastically since ancient times there is no real indication of battlefield area ... nothing much there but a monument. And no place to stop, really.... on coastal road about 20 miles from airport.
• When u ask for critique of itinerary, you need to give ALL facts such as TIME of DAY of arrival, and also departure. For instance u say stop at Marathon for night. Why? Do you arrive at 7pm? If you arrive by noon or early afternoon, with this overly-ambitious wish-list, I say, drink espresso, and drive the 5 hours to Kalambaka, near Meteora. In that situation, my re-do of your Itinerary would be:
DAY 1 - Drive to Kalambaka for the night
DAY 2 - see 2-3 Monasteries -- SKIP Zagorochoria plan -- drive to Delphi for night
DAY 3 - AM See Dellphi ruins & Museum - noon head for Olympia (5 hr drive??) Stay in Olympia
DAY 4 - AM Olympia museum (first) then ruins, Drive down coast to near Pylos (I recommend Hotel ZOE in Gialova)
DAY 5 - explore area and Nestor's Palace. Navorino, Paleokastro castles & town of Pylos
Day 6 - Explore Nature preserves. town of Pylos
Day 7 - Kardamyl
Day 8 - Mani Peninsula
Day 9 - to Sparta, explore Mystra, down to Monemvasia for the night
Day 10 - AM Monemvasia, drive to Nafplio for afternoon &night
Day 11 - explore Nafplio, visit either Mycenae or Tiryns
Day 12 - Drive east toward coast visit Epidaurus, Stop at corinth canal, return car to Airport. Taxi, metro or x95 express bus to central athens hotel (pick one close to Acropolis)
Day 13 & 14 - Athens highlights.
If you think you can squeeze in more places, tell me how, without a Magic Carpet. As it is, you'll be on the move a lot!
