We had 12648 this past January on Oasis, and it is a great cabin. Yes, there are two bathrooms; one just right of the entrance, opposite the smaller bedroom. It is a full bathroom with a stand-up shower. The master bedroom has two entries with doors, and the master bath has a bathtub/shower combo; IMO, the master bathroom is very similar to the Oasis-class JS. The two cabins are essentially mirrored opposites; the main difference is the balcony. 12648 has the hot tub on the far right end of the balcony; 12638 is a little more toward the center. Due to this configuration, I believe 12638 has balcony access from the main room and the master bedroom, whereas 12648 only has access from the main room. Someone may correct me, but I believe that's about the extent of the differences between the two rooms. We sat four comfortably in the hot tub; it may get a little snug with more than that.
