You're thinking of the Murphy bed, which comes out of the wall. People say it gets in your way if it is down but honestly we never had an issue. There's a foot or two to walk around it, but you can stow it yourself we learned, you don't have to wait for your room host to stow it for you. I guess we never needed to be out on the verandah when someone was sleeping in it, but it's definitely do-able. Wouldn't stop me from booking that category room. Just a note, not all deluxe family verandas have a Murphy bed, but the ones that sleep 5 will.
P.S. it's not a fold out sofa bed, it's a single day bed .
