For those who want a brief review:
This ship is beautiful. It was tastefully decorated and as an artist, I appreciated the use of Modern and Contemporary art to decorate the stairwells. I've also traveled on Princess and I found Celebrity to be very similar. There are some things that one line does better than the other, but it was a similar experience.
Now the more detailed review:
Well laid out and designed. Loved the sitting area in the room. Great shower.
