Good morning Ruthanne, yes - this is certainly possible. We have a room with 2 full beds, a room with a king bed and also a twin bed - and we also have our Carriage House which has a king bed and a sofa sleeper. All of our other rooms have only 1 bed.
The king size room we stayed had a big window bench that was the size of a full bed. I would sleep on it on a road trip. A young adult or older kid should be ok.
