We were in a family balcony state room on the 12th deck. I was very nervous about having all four of us stuffed into a tiny room, but it turned out very well for us. The queen bed for my DH and I was more than ample...we are used to a king and we didn't feel squished at all. The couch pulled out into a commodious twin bed and another bed dropped down from the ceiling. Our steward performed all the transformations for us so it went really smoothly.
There was plenty of storage for the four of us to put all of our clothes and then some. We were able to store all of our bags (4 carry on, 1 full size, various backpacks and 4 snorkel gear)under the queen bed. There was a blow dryer, coffee maker and fixings, and a tv(unfortunately we were not able to hook our computer up to the tv for video viewing). There were plenty of mirrors on the walls so we never felt like we were vying for face time.
The room overall was unique and well done. The walls were curvy and pleasing, the lighting was ambient and green (the lights turn off automatically when the stateroom card is removed from the slot).
There was a sliding glass door to the balcony which really kept out the noise.
(in Roatan a very loud band was playing on the pier, when you opened the sliding glass door you could hear every word...when it was closed you could barely hear the bass...it was awesome). There were two chairs and two small tables on the balcony.
The biggest downfall of the room was the bathroom situation. As you enter the room, on either side of you is a shower stall or a toilet area..both are enclosed in frosted glass. While the set up allows for maximum space both in the shower (which was huge) and the toilet it is a little disconcerting to be so open (going to the bathroom in a glass room is a nightmare to me)...There is however a curtain that pulls closed so you are able to change your clothes etc, use the facilities..without being seen...not being heard is another story. Teenagers are not very kind. If however you are open and free with such things, the bathroom set up will be no problem for you. I found it uncomfortable, but not un-doable.
