Just off Insignia from an 11-night Eastern Caribbean itinerary. This was our 44th cruise overall, but first on Oceania. While there were some things to like on this cruise, we were underwhelmed overall. We do not plan on cruising on O again, and certainly not on the R-class ships. Details follow; see near the bottom for comments on accessibility (ADA) features:
The Good:
Service was very good to excellent, reminding us of what Celebrity used to be like 15 years ago or so. Many of the wait staff and bar servers knew us by name and also knew our preferences before the cruise was half over. There were a couple service errors, but the experience was quite impressive on the whole.
Accessible inside cabin. Insides are the only cabins on Oceania's R-class ships that are available with ADA features. ADA features were excellent. Cabin itself was all in gray with no art; lights were fairly dim. A/C was great. Rest of ship was less accessible.
