Ok we are here now and checked into our first night. (We move to SSR tomorrow). 3 adults, 1 two year old and I hate it! It's very cramped. The beds are every comfortable and nice to have a queen in a value because our 2 year old had no space for his air mattress so he is sleeping with us. The issue is the lack of moving space when both beds are down. The distance between the two beds is maybe 18". The distance between the wall and the non-Murphy bed is about a foot. The distance between the end of the bed and the dresser is maybe 2ish feet. And that's it. I will add that the frame of the bed is odd and sticks out beyond the mattress so it actually takes up more space than it needs to but that's the style of the room now.
Wether this is doable for you is completely dependent on your family and preference. If it were just two of us and we didn't need the second bed it would be much more comfortable but with two beds there just isn't room to move.
