My wife and I recently visited Santorini on the Serenade of the Seas. We did the 6+ mile hike from Fira to Oia. We had considered taking a taxi or bus back to the cable car station in Fira at the end of the day, but we heard horror stories about the crowded buses and hard-to-find taxis.
What we ended up doing, along with a group we met on cruisecritic.com, is charter the Anemos for a 3 hour tour of the caldera. Stathis picked up at the gorgeous port of Ammoudi. We then made a stop in Thirassia to take in some of the local flavor. We then stopped at the hot springs for a leisurely swim. (It's not everyday you can say you swam in an active volcano!) After 3 hours, Stathis returned us to Fira port, completely negating the need for a taxi, bus, or a long wait for the cable car.
Captain Stathis was very accomodating, and was willing to modify the itinerary based on what we were interested in doing.
If you are in Santorini, I highly reccomend Captain Stathis and the Anemos. Santorini is a beautiful place...even more so from the water!!!
