Just returned - 5 December. We found Dolphin deck to be ideal for easy access to all parts of the ship. This deck is just above the promenade deck and all outside cabins have unobstructed views. We were fortunate to have a beautiful mini-suite right aft starboard.
On this deck we found the accomodation access forward of the Pitzeria to be very stuffy and stale. No doubt the cabins themselves were properly ventilated, but the difference between forward and aft corridors was very noticeable.
