Welcome to cruise-chat. If you look at
this photo taken by the editor of our sister forum, you'll see he was on deck 12 looking aft (there is no deck 13) and deck 14 is wedged in between 12 and 15. Although this is the port side it is the same as the starboard, and your cabin would be in the first "bump out" down past the cantilevered hot tub. Deck 15 has many places where it is wider than the lower decks.
