Nautica is one of 8 identical ships built for Rennaissance cruise line. Azamara have 3 and Oceania have 4. They are small enough to get into ports which larger ships cannot and therefor have better itineraries. the weather on this cruise had several days of rough weather resulting in missing the first port which was changed to Naples. We did back to back cruises and the weather improved as we headed south. The food on this cruise was outstanding. The main dining room frequently produced meals the equal of the speciality restaurants. This included the lunch menu. Additional meals in the speciality restaurants could be booked at the desk in the terrace cafe every morning.The other outstanding feature was the friendliness and helpfulness of the staff from general manager to cabin steward. This attitude more than made up for the weather.
We chose the excursions from the 3 choices of the "o" life choice before the cruise so we did not have to pay extra to the cruise fare. The excursions were standard and similar to what can be obtained on other cruise lines. If we had paid the prices extra we would have been overcharged by some margin. Similarly the prices for alcoholic beverages were very high.
The cabins on the "r" class ships have small bathrooms. When the forthcoming upgrade of Oceania's ships takes place it would be money well spent if the shower cubicle were extended as well as putting on a folding door. This would be preferable to to cosmetic changes.
