The MV Aegean odyssey is a small ship that recently entered service after a major refitting. because it's small it doesn't have some of the amenities of larger ships (casino, shows, etc.). I would characterize it as a 3 star (bordering on 4 star) cruise.
The ship supports the "voyages to Antiquity" program whereby a pleasant cruise is made marvellous by the inclusion of top-notch excursion and wonderful lecturers.
We sailed from Rome to Sorrento, to Paestum, all around Sicily (6 nights), up the Dalmatian coast of Croatia (Split and Dubrovnik) and disembarked in Venice.
The ship was very comfortable and the entertainers (piano, chamber music) were first rate. the lecturers were superb. The food on-board was OK. Wine (as much as you wanted) was included with dinner. Prices on-board the ship (drinks, laundry, Internet) were very reasonable.
A substantial number of rooms had two single beds (that couldn't be pushed together). That was less than perfect for couples.
The staff could not have been any better. They took every opportunity to make our trip pleasant and our days enjoyable.
The excursions were included as part of the cruise. They were very good (while, as good as a tour with, say, 30 people can be).
The cruise was an incredible value. I don't know how they were able to provide everything that the cruise included (airfare from Naorth AMerica, meals, accomodation, wine, excursions) for the price they charged. It was great value for the money.
