Just returned from the Miracle's 8/2/12 cruise. The Miracle is a lovely ship well maintained, generally everything in working order. VIP embarkation was smooth and stress less. Debarkation was not quite so stress free but close.
Our cabin was fairly spacious, the bathroom contained a whirlpool tub. Plenty of storage. Very comfortable. The state room staff were friendly and very helpful. The dining room staff were equally helpful and friendly. The food was OK, nothing particularly special and oddly enough the portions were notably larger on the last night than previous nights. One does not travel on Carnival for the food.
Carnival has a great kids program. Even though there were literally hundreds on board, we hardly saw any of them.
The cabin was very comfortable. Not as luxurious as some ships but spacious enough with plenty of storage and a great double balcony!
