We are just back from our trip. Thank you everyone for their advice. We had a wonderful time the Peloponnese piece was great. We rented a car and departed Athens in the morning. Stopped at corinth canal for a photo opp and then headed to Epidaurus which we really enjoyed. We then continued on to Naphilo and picked the King Othon II Hotel to stay at. Rooms were clean and our hostess friendly. Steep steps with no elevator so we left our luggage in the car. Also you need to park in the public lot as street parking is extremly scarce. Naphilo is a great town to stroll, buy worry beads have drinks on the water. We did not tour the fortress this next morning (it was hot and we slept late) but headed out to Mycenae. Also a great site. Continued on to Olympia - got there by dinner. Stayed at the Eurpopa was functional, clean and fine with the surprise being a great and relatively reasonable dinner at their outdoor taverna. We visited the site the following morning, and then headed back on the road. Went over the new bridge down the coast road and landed in Delphi early in the evening. We stayed at Hotel Varonos - our room had a great view of the mountains and Valley (again no elevator, saw Delphi the next morning and then drove back to Athens airport for the flite to Crete. Everyone was incredibly friendly, even when we got a bit lost at times. The country is beautiful and the history really interesting.
