First let me say that the ship is an engineering masterpiece. If you are interested in engineering, then you have to check out this ship. It is a floating resort. Beautiful construction and smooth. Never felt the engines or sea much at all. :)
The one problem with the design is that you can't get very close to the water unless you have an outside balcony. We felt like we were in a hotel; not on a ship. There are very few views of the water except on the 15-16 floors; way high above the ocean. We might as well have been in a hotel looking down on a beach. :(
One problem with this boat is that the elevator traffic in the middle of the ship is way overloaded due to the fact the Windjammer, Viking Lounge, Boardwalk, 3 main dining rooms, Guest Services, sports deck, and casino are all aligned with the mid-ship elevators. Poor traffic design. This could be mitigated somewhat if they install upgraded logic on the elevator firmware to keep them from bunching up. But there is a lot of mid-ship traffic due to the design.
