Had great week on RCCL Navigator from Rome. Had booked flights and transfers with RCCL and everything went very smoothly (slight delay on way home). We were family of 6 in a family oceanview and it was fine, just really somewhere to sleep with the added bonus of a fantastic view.
For our needs, Navigator was a great ship. I agree with other reviews on the friendly staff, great food, plentiful activities, fantastic entertainment. Our teenagers disappeared every day to meet with friends, even staying on board during our last stop in Chania. We had arranged private tours in Ephesus and Athens and our drivers/guides were great.
We ate mostly in the Windjammer rather than the main dining room as self-service suited us. At breakfast and lunch the Windjammer is very busy and it can be difficult to find a seat, but in the evening it is quite relaxed.
Our cabin steward was very helpful and attentive as he had to make up the sofa bed and then stow it away again every day. Staff never passed you without saying hello. Entertainment was first class with "Beatles", "Il Divo", cabaret, mime, ice-skating and lots more. All in all a great holiday and highly recommended.
