We booked a private tour of 6 for Santorini,  Greece from our Port off Norwegian Gem.  We were promptly met, and off we went in a comfortable, air-conditioned van.  Theodore was very, very, knowledgeable about all aspects of Santorini, as he is from the area himself.  We were taken to all the highlights and more.  We were able to stop, take lots of pictures,  and Theodore took pictures of our group too.  I would love to return again,  and will definitely rebook to see more, but only with Theodore!! He was wonderful and very pleasant.
