We had a very enjoyable cruise on the Pacific Aria. Our cabin (9090) was quite spacious with a balcony & spa bath. The stewards were fantastic with daily servicing and turn down service, even leaving a cute towel animal one evening (a penguin).
The activities were continuous, but the booking process was a bit frantic - queues of people waiting to book restaurants and activities upon boarding. We boarded in the first half hour and got a place on every activity and restaurant, but there were only a few places left in some cases.
The restaurants were average, with Waterfront food and service being not good at all. The service at Salt was excellent, and the food was very good. The bar service was very good, and there were plenty of staff around asking if you wanted a drink.
