My husband and I just returned from a 7 night Bermuda cruise on the Norwegian Dawn. This was the second Bermuda cruise that we had taken on the NCL to Bermuda.
We stayed in an Inside cabin, #9725, which was at the stern of the boat. This was good in that we could take a very close elevator and arrive at the Garden Cafe or either of the dining rooms without having to walk the length of the deck. Our room was small but we expected that. It was larger than the inside cabin we had on RCCL in January and had more storage. The bathroom was large enough and the shower was large by cruise ship inside cabin standards. We were pleased with our room. We did find that separating the beds gave much more room in the cabin.
The cruise was calm so there was NO movement at all on board. Some cruisers think that being on a higher deck mid-ship is best. I have taken ten cruises and have been in cabins all over the ships and find that lower decks are fine and actually have less movement. Deck 9 was closer to the top of the ship (13 decks) and was great. I wouldn't hesitate to take one on deck 4, however.
