I decided to try MSC after I completed a status match (which MSC offers all the time on their site). I was matched to their top tier (diamond) from my Top tier status with Princess. I went in with an open mind and low expectations. I was pleasantly surprised in some ways and utterly disappointed in other ways. This is my mixed bag review.
On the positive side:
The ship is beautiful, elegant, well designed and well kept. There are several pools, chairs, and hot tubs. The theatre was large and attractive. The dining staff was professional. not overly attentive, but consistent.
The cabin was attractive, small but efficient. The Aft balcony was the highlight and why this cabin was chosen. It was clean and organized. The curved glass shower door added a touch of class.
