For our last cruise we had cabin 5140 on the Disney Wonder which is a category 7, navigators verandah. The cabin is the same size as the cats. 5 and 6 but the verandah is a little enclosed, but not totally. To me it didn't make that much of a difference. We were three adults which is all the cabin will hold. The pull down sofa bed was not the most comfortable but it was ok. All the cabins have a queen bed which is really comfortable. You can request two twins in it's place which the girls in our cabin did and they said the beds were ok. The split bath is always great with three gals sharing a cabin.
I would love to hear about other cabin categories and reviews.
