Although the ship was full, there were always lots of seats in the observation lounge and around the pool. The only time that you noticed a full ship was sometimes in the buffet restaurant at breakfast time.
We were looking forward to the food on this cruise. Other than fantastic meals in the two (free) specialty restaurants, we were extremely disappointed. The buffet food was often cold and was at times under-whelming and at times, unpleasant, (especially at breakfast time). The deserts were not as good as we have had on other cruise-lines.
The dinning room food was ok but nothing amazing. There were several places onboard to fill up water bottles, which was good and the coffee machines were also good. We have recently done an Azamara cruise and felt that the food was better there (than this Oceania cruise).
