We were assigned cabin D523 an AA category minisuite after booking an AE GTY. We were very pleased with the assignment. The location was very good as it was midship, but on the aft side, so it was very close to the mid-ship elevators while also not being that long a walk to the aft elevators. We found the space to be generous and thee overall layout to be excellent. The bathroom was decent-sized with a roomy tub and plenty of room for all of our toiletries. The closet and clothes cabinet was outstanding, with plenty of room for our hanging and folded clothes (and we are notorious heavy packers). The bedroom area was ample with plenty of room to move around the large bed and bedside tables, which also had a couple of drawers and a shelf for storage. The desk area was sufficient for all of our gadgets, including our laptop computer. The bedroom flat-screen TV was mounted in the top of the bar unit, which included a small refrigerator tucked away. Moving further into the cabin was the sitting area, which we found quite spacious. It easily accommodated a full-size sofa, an armchair and a cocktail table. There was another TV mounted above the additional storage unit that was the backside of the sleeping area unit. The flow was quite nice and there was ample lighting specific to each area that could be controlled separately. Moving beyond the sitting area was the balcony. The balcony size was sufficient and accommodated two chairs, two reclinable loungers and a cocktail table. While there is a great deal of debate over the dolphin deck balconies due to the fact that they are "open" in that they are staggered out, allowing those with balconies above to be able to look in, we really enjoyed the open balcony. On the transatlantic crossing, we used our balcony almost every day. Being on the starboard side, we had nearly full sunshine the entire day. Also, when I did glance up at balconies above, when I did see others on their balcony, they were gazing out at the ocean, not down at me. I would book another Dolphin deck balcony in a second. We experienced very little hallway noise and no noise from the cabins on either side unless we were both out on the balcony at the same time. The only downside that we experienced was, on the crossing segment of the sailing, when there was ship rolling from higher winds and seas, we heard a grinding/creaking noise from underneath our cabin. From our walks on the Promenade deck and a quick glance up, we realized that the tenders and survival boats were suspended below the Dolphin deck, beside the Emerald deck and overhanging the walking area of the Promenade deck. As the ship rolled, the tender under our cabin would move within the mechanism that held it suspended above the promenade deck, which caused the grinding/creaking. Fortunately, after the first tender port, when the tender below us was put back in place, the noise was no longer present.
