Hi, Judy!
The Cabins at Fort Wilderness are so much fun.  With a great cabin and so many resort activities, you may never want to leave!
Here is the sleeping situation:  In the bedroom, you will find a double bed and a set of bunk beds.  In the living room there is a pull-down Murphy Bed, which I like better than a sofa sleeper.  
In addition, your cabin will have a full bathroom, kitchen, dining area, and outside you will have a deck, picnic table, and even a grill!  Seriously, this cabin is a self-contained vacation!
Have a great time at Fort Wilderness.  If you need information on activities, dining, or anything else at the Fort, 
drop a note to Disney Mom Kay.  She loves staying at Fort Wilderness and knows every inch of that property!   Wishing you a magical vacation.
