Buying a TT, Bunk "Room" vs Bathroom door to outside

Is the "bathroom with an outside door" always a 2nd bath? If so, I change my first opinion. I would find the dumping annoying.

But if it's a choice between one bathroom with outside access and a bunk bed room, I would take the outside access. Again, I think letting the kids use tents and have access to the bathroom late at night will be more fun than a bunk room.
