We decided to cruise on RCCL because we were traveling with young family members and we thought they would enjoy the Brilliance of the Seas. We had a good time because we were together, but we won't cruise with RCCL again. The ship was very noisy with no quiet spots anywhere. The food was mediocre at best and usually worse than that. The only indication of the Christmas season was the decorations, no music, shows or anything else to suit the season.
We did enjoy the production shows although a nod to the season would have been nice.
So it's back to Princess for us.
The cabin was large enough but we found the floor plan lacking common sense. Doors to the cabin, closet and bathroom all converge. When the beds were separated access to the balcony was difficult.
