We did this cruise as we wanted to do the Norwegian Fjords, & booked a Superior Deluxe Balcony Cabin ( C324 ) on 12 Deck. Our cabin was very comfortable, & we didn't have any problems with it.
The embarkation was the best we have ever experienced ( our 17th cruise ) & took less than 30 minutes to board from arriving at the cruise terminal. On arrival at our cabin our luggage was already in it! Well done everybody at Southampton.
The ship seemed to vibrate a lot, especially on Deck 5, 6 & 7,at the Atrium, as well as the buffet on Deck 16 ( It was so bad that if you ordered a glass of milk, by the time it arrived it was a milk shake!)
Very comfortable, no problems
