Let me begin by stating that this was our 10th cruise with Oceania. My comments are our opinion and based on personal experience on the December 21, 2019 Sunny Holidays Cruise on Oceania Sirena. Oceania is not what it used to be. We observed and experienced a large discrepancy in the food from previous sailings. Chilean Sea Bass, Caviar, Almond Croissants and high levels of meat were a given previously. They were lacking on this cruise. In fact, several people complained vigorously regarding the steak. Oceania has been highly rated for its food. That did not appear to be the case on this cruise. New year's Celebration were around the pool. Now divided in different areas. The descriptions of the shore excursions did not match the material given to the guides. We had a excellent guide and yet his description as written of the day did not match what we paid for. Yet, when we complained to the destinations desk, we were told that everyone loved the guide. We did too. However, we did not get what we paid for. The main dining room and the Terrace grill appeared to be short of waiters. It wold take two or more hours to dine in the dining room. The Canyon Ranch Spa was previously always a wonderful experience. That is no longer there, being replaced by a spa where, there are basically all recent graduates of schooling (as stated by a technician) . We were not notified in advance of this change. Regarding the decoration of the ship. The redecoration of the ship is beautiful, and our cabin stewards were excellent. The showers are very small, yet the sofa was comfortable. Regarding the entertainment, we understand that it can not be compared to the larger ships, however, three nights of movies for entertainment is not acceptable. The stand up comics and Stuart were excellent, however enrichment activities were minimal. Tender workers were excellent. Cruisers who experienced this for the first time would not have noticed the difference. Lastly, research the ports. When it says Belize, it does not mean that you will actually be in Belize where you can readily tour, instead we were taken to a water park, away from everything in Belize. With that said, there were constant concerns on the cruise from past cruisers, even those who had 17 sailings regarding the downgrade from previous cruises. We were very disappointed with this cruise. The previous comments reflect our opinion.
