We joined the ship in Istanbul. Embarkation was quick and smooth. Don't expect any kind of welcome in board; no senior staff or welcome drink.
The ship is beautiful and the service and house staff really do a great job. Senior staff are conspicuous by their absence. For a ship of this size you would expect them to be more visible, but they are not.
The food was excellent in all venues. The entertainment was generally ok too, except the "night club". Handing round an iPad for people to choose their own music lead to a haphazard playlist that resulted in a mostly empty dance floor and club.
Cabin was excellent and the bed was the most comfy bed we have ever slept in at sea!!
Walked up all 700+ steps. Watch out for the donkeys!! It's also a bit smelly with all the donkeys and their deposits!
Santorini is beautiful. Lots of nice shops and restaurants.
Very commercial and over developed for the package tourists.
