In the planning stages of our next cruise and we will have our 2 adult DDs with us this time. The sofa bed worked well for my one DD on our last cruise but I am wondering if the ceiling pull down bed would work for my younger DD. She is about 5'6" and weighs about 130 lbs. I could book the family stateroom but that would be more than $1000 extra. Any feedback would be appreciated.
