This was our 7th cruise with Oceania and second on Riviera. We love this cruise line. The food in all venues are terrific (4 specialty restaurants - all included in your cruise fare) plus the Grand Dining room, Terrace cafe and a very casual spot called Waves. The entertainment team was very good on this cruise and we've complained about that on previous cruises. We enjoy the string quartet as well. Service, as always, was wonderful. Everyone is so friendly and skilled at their work. Oceania does a really good job of training staff. The ambience on-board is lovely. We appreciate knowing at the beginning what we will be paying rather than paying for each thing individually. We don't drink so we also appreciate not paying for alcohol and being able to choose a different amenity. We have two more cruises already reserved on Oceania so we will definitely continue cruising with Oceania and highly recommend it to the adult traveler.
