We prefer slightly smaller ships but in the same or better class. This was our first exposure to Oceania and we were comparing this experience to Seabourn. The ship was very nice and the Penthouse Suite was just a bit larger than the standard suite on Seabourn.
Food was very good overall and the 4 specialty restaurants were a pleasant surprise--we tried all of them and a couple of them more than once. But I did notice they used a lot of salt in their menus--I would have preferred a bit less salt.
Cooking classes were fully booked so I did not get to participate in those.
We were offered an upgrade to the Penthouse Suite and took the upgrade. Room was excellent except for two things:
Sliding Door to walk in closet could did not have a latch and we had some rough seas--rolling. The door kept opening and slamming shut. Had to stuff a slipper in between the panels to keep it closed.
Hair Dryer and lighted makeup mirror were not compatible with the outlet at the vanity--only worked at the desk--an inconvenience.
