We just returned from our first Oceania cruise. (This is our 5th cruise). We did the South Pacific starting and ending in Papeete Tahiti for a 10 day cruise.
We absolutely loved Oceania. We would sail Oceania again in a heart beat and most of the fellow travelers we talked to felt the same.
The staff are plentiful, kind, caring and sensitive. They serve the food in buffets to keep you safe. They change the linens on lounge chairs to keep everything safe and comfortable. I have never had such consistently wonderful service on a cruise. I felt spoiled each and every momment. I had to go to the medical clinic and received excellent service (ok the bill was pretty high-like USA healthcare prices!)
Loved the room. Balcony had two comfortable chairs. Full bath and full separate shower. Bed and bedding wonderful.
