I'm traveling to Greece solo in May of '14. I plan on taking a road trip from Athens to Olympia, Delphi, Meteora and back to Athens. The dates will be May 12-15. We will be visiting UNESCO world heritage sites, ruins and museums. I have found a driver who will take us for a fair price. If we split it at least 2 ways it would be the cheapest/convinient way to go. I'm 32 years old, male and I get along with everybody. There will be alot of drive time, but it will be worth it.
