Very tight fit for two adults and two teenagers. Well positioned on the boat. The beds are three twins pushed together and one bunk that folds down - not a whole lot of leftover space. Best way to increase space ask to have the small end tables removed - and I always have the mini bar removed. Read entire member review.
My sister and I had inside rooms at 9163 and 9157. They were a little smaller than other cruise lines, but had plenty of storage. The shower was nicer than most too. If you are tall though the toilet may be difficult to use. You have to be slightly turned; if you are not your knees hit the wall. The beds were very comfortable. Read entire member review.
