We liked the itinerary. But we're quickly disappointed by things onboard starting as soon as we saw our Penthouse Stateroom. Nothing was different from 4 years earlier and now the decor was tired and the room overall outdated. Then as soon as we pulled out of port we were informed that we were on a "sick" ship. A number of the crew and passengers had norovirus and the onerous sanitation processes had to continue until no one had reported these sick symptoms for 72 hours. This went on for the entire first week of the cruise. The food we were quick to discover, was not of the same high quality we had experienced on our 4 previous Oceania cruises. The quality just wasn't there. And, the crew were often surly and short with the guests. NOT ACCEPTABLE. Then, due to weather issues, instead of the final port before returning home being Bermuda, we docked for 2 days in Nassau--the poorest, cheapest port Oceania could have selected. Everyone was fed up by then. I heard many, many complaints from the passengers--many of whom had never before traveled with Oceania--say never again. Back to Crystal!! How sad. Oceania, you owe your long time supporters an apology. Your major distinction was high quality food and service, and you have lowered your standards to a level that you will lose your image and position in the cruise world.
