Might I suggest the Treehouses at SSR? They have roughly the sq ft of a 2 br, but sleep 9 plus one under three. The master bedroom has a Q bed, there is a second Q bed, a room with 2 bunk beds, and a sleeper chair and a full -sized sleep sofa in the living room. There is a deck and I think this would be a much better option than the value 2 br, which would hold your family, but be very cramped.
The THV require the same amount of points as an SSR 2 bedroom due to floor size. There is a recent post on Mousecellanous by BirdsofPreyDave with pictures to give you an idea of the housing.
