Go with an open mind. We read some of the reviews and were apprehensive, we needn't have been. The ship is a little older but immaculately kept. We booked an aft cabin 9078 and were very pleased indeed. It wasn't huge but had enough space, the bathroom was compact but adequate and the balcony was great for relaxing with lovely views.
Embarkation was fine, the food was more than acceptable and the all inclusive drinks included premium brands so all in all, great value for money. All in all, it was a chilled experience without the formality that some cruises inflict on you.
Nassau was OK for a walk around and we were diverted to Key West because of Hurricane Matthew - transport was laid on free of charge to get into town so all in all, we were pleased with the alternative.
Great cabin, quiet and enough space. View from the back on the balcony was lovely and the whole cabin was spotlessly clean. Bathroom compact but adequate and I would go for 9078 again if we sailed on the Norwegian Sky.
