We booked a one week eastern mediterranean cruise on Celebrity Silhoutte from Venice to Kotor, Santorini, Athens and Katakolon.
Did exactly the same cruise on another ship years agon so we knew what to expect in the ports.
Cabin:
Loved the layout of the Sky Suite with extra space and huge bathrooms but never again would book an aft cabin due to massive soot problems every day. Balcony was nearly unusable.
