Greece was my bucket list destination. Because we wanted to see a variety of islands and only had a short time we chose the Jewels of the Cyclades Cruise with Variety. I am glad we did. First off. The ship is charming and because of its size you spend a lot of time at port instead of getting to the port. Our Cabin was necessarily small ( its a small ship!) but well appointed. I chose Cat A because i like the outside entrance. The staff is fabulous, very accommodating. The food is fantastic. The upper deck is magic.
Second the Islands. Mostly you sail early am or late at night and so you get to spend a lot of quality time at each island. That said. Do your homework or take the excursions. The excursions are small groups and not too expensive so I recommend them if you don't know the islands or don't like to strike out on your own. We tend to go off on our own so I did research and we mostly explored each island either by bus on foot or rented a car (Make sure you have your International Drivers Cert) Must see -Go to Rakentia on the island of Folegandros ! you can take a bus from the marina and then walk there from town)
Don't miss the excursion to Delos.
Upper Deck Category A. We paid extra..my husband fussed at me about it.. until we saw the cabin. it has an outside entrance and you can stand at the rail outside your cabin as you sail the Aegean !
