Only a few 11B staterooms are “sideways” rooms; most are the typical layout. The sideways rooms have the door entering into the middle of the room — essentially into the “living room” area with the couch; the bed is to one side and the bathroom and closet to the other. A typical layout has the door entering at the end by the closet and bathroom, proceed into the living room area with couch, and the bed is at the far end opposite the door. I believe the actual room layout is the same, the difference being location of the door entrance into the room. But again, only a few interior rooms are “sideways.”
Enjoy your cruise!
