Haven’t cruised yet, but booked this independently for our upcoming cruise. I think the VV shore thing is exactly the same. You take a ferry over with everyone and there are then guides on the island - here’s the description I received -
“at Delos The guide distributes the entry tickets to the archaeological site, to the group members and after the ticket control, the group is gathered at the
Agora of the Competaliasts.
Guided Tour Exceptional mosaics, well preserved marble columns and amazing wall
paintings are just a few of the featured highlights of a rich man's house. A few meters further away we admire the beautiful statue of Cleopatra, decorating the entranco of her residence. After a short stop at the house with the Trident, we reach the Theatre of Delos and the public cistern of the city. This is the and of the route in the urban part of the city, which then follows the main street to return to the market and the Sanctuary zone. The Stoa of Philip, the donations of ancient colobri ties, The Propylaia, the Colossus of the Naxians and The Tomples of Apollo are the monuments we admire before our last stop in front of the Sacred Lake and the eternal Naxian Lions.
Free Time
From this point on, our visitors continue individually for about 30 with the
options of either visiting the archaeological museum, the museum shop.
