All the cat. 3's have a frosted glass sliding door that separates the living room from the master bedroom. There is a pull out sofa bed in the living room that sleeps 2. The mid ship cat. 3's also have a murphy bed in the living room, while the other cat. 3's have the murphy bed in the master bedroom. If you plan on using the murphy bed for one of your daughters, then yes, the mid ship cat. 3's will offer more privacy. All the cat. 3's have 2 bathrooms - the master has double sinks, a whirlpool tub and shower. The other bathroom has a single sink and shower.
Hope this helps!
