I went on the Epic with my 3 sons and my parents. I booked for 2 mini suites thinking to split one kid with the grandparents and the other two kids and me on the other mini suite.
The staterooms were TERRIBLE!!!!! the size was pretty small and we could hardly walked around (the three of us). It would be ok for a balcony size staterooms but not for a mini suite. The walls are curved and it makes an useless layout as it takes more space.
The worst part was that the tub (and shower) is separated from the bathroom by the entrance way and it doesn't have a door!!!!!!! Incredible but true!!!! You are bathing covered only by a curtain and if somebody comes in they can easily see you naked! Then, when you finish showering, you need to stand in the entrance way to change your clothes, closing another curtain so you can have "privacy" from the others in the stateroom.
