We were on deck 15 port side last month. It would be my last choice. My comments are not complaints, I felt very fortunate to be in that cabin.
The deck above is the wake view bar so there were so there were guests looking down at us and often wanting to have conversation.
Deck 17 aft is the cigar smoking area and is very well used.
During the night between 1 and 2 the decks above are washed down.The noice isn't what bothered us so much it was the cushions and the deck were soaked and stayed that way most of the day. We tried taking in all the cushions at night but that didn't always happen. The furniture also was soaked so they were in very poor shape.
The huge plus was it was a short walk up to the bar for drinks and coffee in the morning.
I agree deck 14 would be my choice.
