So I was just checking out our cabin and it looks like it has a queen, single convertible sofa and a pull down bunk. This is going to be an issue. I don't trust my 4 year old in the upper bunk, especially if she gets out of bed in the middle of the night. My 9 year old is disabled and cannot climb up to the top. What other sleeping arrangements are there in cabins that sleep 4? Could we get an extra cot in the room? We booked through a TA and she is looking into it but thought I'd check here, too.
