Cruise-PC

Has anyone arranged a private tour from Piraeus to the Corinth Canal? We’ll be on a back-to-back cruise, arriving in Piraeus at the end of the first cruise on November 2nd, and we're thinking about visiting the canal. Is this feasible? Has anyone had experience with disembarking and reboarding in Piraeus? According to Google Maps, the canal is about an hour from the port. I’d love to hear about anyone’s experience with this. Thanks!
