We went last year, and didn't really like them. They are clearly just two standard rooms, with a wall missing, and a small kitchen.
It was hard to have a parents room, with 4 kids. 2 teen boys, a teen girl, and 4 yr old girl. There was really no privacy for the girls/boys. We ended up putting one of the fold out chairs in our room, squeezed it in there, so our 4 year old could sleep, when the other older one's would be watching tv, or hanging out.
Next time I need to house 6 people, I will just get 2 connecting rooms.
Others may have liked them, which is what is so nice about Disney, but we wouldn't do that again.
