Our instructions were, upon debarking the ship we would be PICKED UP at the Sea Bus. NOT so. Turns out that the excursion DOES include the Sea Bus Transfer, but staff at the Cruise Port seemed unaware. After using the Sea Bus to the Old Port, we had to determine by asking the transfer boat crew what to do. They pointed out the very crowded check-in kiosk. Thereafter, things worked well. The tour itself was conducted by a very knowledgeable former archeologist who had worked the site, and was able to provide LOTS of detail. However. Delos is VERY popular and a vox system for each of the fairly large groups would have gone a long way to making it much easier for everyone in our group to hear the complicated, and fact-filled narration.
This tour was not as advertised. Our paper work stated we would be picked up at the location right outside of the Cruise ship. No one was there. After several phone calls we had to make it on our own by way of a water taxi to the Old Town to pick up the tour to Delos. The tour itself to Delos was very enjoyable. Our guide, Alexandra was wonderful and full of interesting information. We basically did this tour on our own. It is not set up for Cruisers.
