I would appreciate opinions on my itinerary. Is this to ambitious? It is my husband and I and two teenagers. We get into Athens at 1630 and was thinking about picking up a rental car from the airport and head to Kalambaka that night, not to waste a day, stay two nights in the Kalambaka area,,one night in Delphi, one night at Olympia, seeing Meteora, Nafphlion, Mycenae and Corinth on the way, and then turn the car in and two days in Athens. Also debating if two nights on Hydra are worth the time and expense or if we take two nights in one of the fishing villages, Naphlion? if that would be better.
Maybe you need to lay out things a bit better, but in the first breath you talk about 6 nights, then mention two more later. Considering that you arrive on day 1, how many nights do you actually have in Greece? Also, at what time of year are you going?
Regarding your itinerary so far, if you arrive at 16:30, take an hour to get the car and off the plane, you are talking about leaving the airport area at 18:00 for a long drive to Kalambaka (4 hrs?) in the dark, on strange roads, driving with the Greeks (love'em but crazy drivers), all the while jet lagged from a long flight...Not something I would recommend. Find a hotel in the forst city north of the airport, stay there and get an early start to Kalambaka. Doing a night in Delphi, then Olympia is pushing it, but can be done, Corinth to look at the canal is a quick stop, but Mycenae needs a morning or afternoon of it's own, to much to do as an hour stop on the way. The same could be said for Epidaurus which you didn't mention, and the Meteora (up at Kalambaka) will take at least a half day to do a couple monastaries.
Thank you for your voice of reason. We are going June 8-13/14? I haven't bought our hop to Rome yet. we were thinking roughly a week in each place. We fly home to the states on the 22 of June.
