We have not been there yet, but have a reservation for early November.
I was told that it has 2 queen beds and a pull out sofa bed. They are a little bit larger than the standard room and have both garden and pool views available. No difference in price for the view. We went with the deluxe because of the sofa bed and then we would not have to get a roll-away (we are also a family of 5). I am not sure if there is an extra charge for a roll-away or not.
We got it with the entertainment book discount price of $149.50 (plus tax) per night.
