Thanks,Dick. Yes, Booklady, it may be good to learn from others' experiences, and I've visited Greece 12 x, importantly on 9 trips I took along "newbies," so I know what works on one's initial trip. Yet despite our protests, you keep trying to "pour a quart into a pint bottle."
NO, you can't get to Olympia on your short time- frame. and NO you must not short-change Athens .... she's been waiting 4,000 years for you, garnering all her treasures to awe you... and you want to give it 24 hours? At least give it 36. And NO it's not a good idea to start a drive to Delphi at 3 pm that takes 3.5 hours ... Can you google Athens sunrise/sunset?? You will see that on Nov. 21, the sun sets at 5:09. Such fun to drive in the dark, in the mountains, on an unlit road with no guard rails. Whee.
As it is, with so many things closed on Mondays, you'll have to strategize carefully. Here are some thoughts, based on when things are open & when it's good to drive:
SATURDAY AFTERNOON -- You'll arrive too late to go up on Acropolis, but I suggest you get a hotel NEAR it, on S. Side is my choice -- Look at Herodion, Phillipos, Airotel Parthenon, Hotel Hera. Before Dark u can stroll over to Temple of Zeus & Hadrians Arch, walk down Lysikrates to Lisykrates Monument, (or to Panathenic Stadium? ) have a nice dinner, ask hotel if any places have music in EARLY evening.
SUNDAY -- 8:30 - 10 ACROPOLIS; taxi to NAT. ARCH MUSEUM 11 - 2. Lunch & feet up! Any time between 4 - 8 go to ACROPOLIS MUSEUM (it's not govt run - open from 8 AM - 20:00 = 8pm daily except Monday)
MONDAY - 8:30- 10 AM... Ancient Agora (use Rick's DIY); Check out of hotel; get car at nearby office, get GOOD directions to Highway!! 11 AM - drive toward Pelopponnese. Jump Off @ Isthmus for Corinth Canal & back on Hiway; Exit to R after 10-12 miles for ANCIENT NEMEA. https://nemeangames.org Get your "Sacred Games" thing on, here... temple ruins, theatre & stadium! The official website says open all days of year, in Nov., 8 am - 6pm. But HAVE your ATHENS HOTEL Call on SUNDAY to Be Sure. Arrive NAFPLIO about 2 pm? Explore old town in Afternoon. Get to seafront cafes in time for sunset.
TUESDAY - Don't miss GOOD small Nafplio museum (45 minutes) ... MYCENAE??? TIRYNS? Enjoy Old Town walks around point of peninsula. Enjoy
WEDNESDAY -- check out, drive E across "thumb" of Pelops to EPIDAURUS ... then up the coastal road to Isthmus back on Big Hiway towards ATHENS. Here's where you could do your Delphi thing == it will be maybe noonish, 1 pm. You can get to Delphi by 4:30 or so, still light. Check into Delphi hotel before dark.
THURSDAY -- Get to site at 8:30, to Museum by 11, leave by 12 back in ATHENS 3:30 or 4. NOTE: Depending on rental agency, You may want to drop Car @ AIrport just to avoid traffic & take Metro or x95 bus to central Athens.
ALTERNATIVE -- If you decide against Delphi, you can return to Athens for Wednesday night and if Thursday is sunny, you could take that AEGINA ferry trip I suggested earlier (on OPEN-DECK ferry) just to have the "Greek Ferry experience." Here's a video from June -- but the sights/sites will be the same. http://www.flickr.com/photos/36264706@N03/sets/72157621604646139/detail/
If this doesn't please, I leave it to someone else, I'm done here.
