This is my second cruise, aboard the same ship Riviera. However it was my first time as a solo traveler. The ship itself and everything included in it was wonderful! However, the service was very poor. As a solo traveler, I was virtually ignored when it came to service. So badly so, that after the first two reservations in the specialty restaurants, I cancelled my future reservations since I did not want to go through such treatment again. If you are seated by yourself, you will be waited on, eventually. But only after you say something to the Manager. Even after that the service will be slow, the wine steward will not wait on you, and forget having your water refilled or even asking you if you would like dessert. They make it obvious that Oceania simply does not want you there as a solo. In the buffet it was not much better. You serve yourself and always have to get your own drinks. For several days I would get my own water and coffee and then a head waiter saw me doing this .and asked if he could help. I explained to him that I knew if I wanted anything I would have to get it myself. He was apologetic, but full of excuses as to why I was ignored. After that, I did notice a small improvement in the service. I can only assume he must have said something to the staff. This treatment was everywhere on the ship. Everywhere!! If you were seated by yourself, you were ignored. I did find a bartender that was the complete opposite and treated me like everyone else, so there were exceptions. But if you are a solo, do not travel on Oceania.
