First off - it is a beautiful boat - the public areas are gorgeous - as usual the cabin staff and wait staff are exceptional.
The food is amazing, - even though we are not foodies. The four special restaurants are top class - we enjoyed the main dining room which is a lovely room - big and light and airy. We enjoyed the dining in the terrace - especially outside. The waitstaff there are so nice and really take care of you.
The cabins are very comfortable - the bathrooms are much bigger than in the R boats, have a bath tub - which didn't do anything for us - we didn't use it. The shower seemed to be about the same size as on the R boats (small).
Usual Oceania issues - Internet and excursions ridiculously expensive! Entertainment limited (difficult to bring in really good entertainers with only 1200 people paying the freight.) Senior staff somewhat "aloof"
Getting off in Miami was a nightmare - we were held "hostage" for about an hour - no idea why - no proper explanation. Oceania really upset their clients - especially us - we missed our flight back to California and had to standby all day to finally get out at 8pm - getting home about 1.30am!
Overall the cruise was great - pity about the end - we left the ship mad!
