Cabin 7690 on the Mariner. This is an AFT balcony cabin (behind the ship). I understand these aft balcony cabins are the same size inside as other balcony cabins on the ship. However, two advantages: 1) view of both port side and starboard side. 2) the balconies are much bigger: in fact, unlike other balcony staterooms, these have 2 lounge chairs in addition to the regular 2 regular chair provided! We spend a lot of time on these lounge chairs sipping wine, enjoying the view and reading our books!
