I always book an outside cabin - it is wonderful waking up to the sun in the morning - something we have missed sorely this summer in the UK, so well worth it! We also were on P deck (5) and D deck(8, 2nd cruise) both were lovely big cabins (I think they are about the same throughout the ship). and quiet though we were disturbed by a high pitched noise overnight from the ship stablisers when they were deployed P175 (deck 5). As I have Tinnitus the pitch of the noise (although acceptable to my husband)was terrible for me. We were helped out of the cabin to another with no fuss and much efficiency. The ship was full and the only available cabin had a window that felt like you were looking through a fog, but we were very grateful.
