Delphi and Olympia Escursions

[sauertea]

Hi, we are taking the Star Breeze--Venetian Passageways in October. Wondering about the best way to see Delphi and Olympia. The Star Breeze offers a number of excursions. We are pretty independent travellers so we are comfortable doing our own thing. That being said, we will be docked in ITEA for a relatively short period of time, so wondering if the excursion is the best way to go in this case. We dock in Katakolon from 8-5. I understand that there is a tram from the port to Olympia. In this case there seem to be more alternatives to the excursion. Any thoughts or suggestions for either port? I think my biggest concern is making sure that we don't end up stranded and unable to make it back to the ship. Thanks in advance.
