First the ship ----
This new ship is decorated to the finest detail. It is beautiful. Cruise the 'net' to find photos. Whatever you see online, won't do it justice. The cabin size was more than adequate with more storage space than required. I would NOT book a suite on this ship - a waste of your money. When one initially views the ship from the outside the first thought would be "Where are the balconies which are promoted?". The Catherine has an interesting concept, which I would label 'internal balconies'. It is really a separate sitting area with windows that electronically open with a screen (they label a mosquito net). It was a nice space to relax. My only criticism with our cabin would be its location. One would think with a new ship, the amount of noise and engine vibration toward the stern of the ship would be reduced. Unfortunately, this is still an issue. I would NOT recommend a cabin in the rear quarter of the ship, if one is 'sensitive' to noise and vibration.
The public rooms and lounges on the Catherine are wonderful. I do not agree, however, with 'Cruise Critic's' discussion about the pool. IMO, it is a waste of space. The pool is within the bar. Thus, one is on 'display' when utilizing it. This probably lead to the lack of use. During a future 'refurb', I would recommend UniWorld remove the pool and extend the space within this wonderful bar/lounge. Also, during this 'refurb', something should be done to insulate the dining room. When it is full, it is very noisy.
