Hi Alexus, 
You have several options for your family of 6. 
Disney's 
All-Star Music Resort is the only Disney
Value Resort to offer family suites, which sleep up to 6 Guests each. These have 2 bathrooms and a small kitchenette. You can also rent two standard rooms in any of the 
Value Resorts. With 2 adults and 4 children, you can request connecting rooms which have an internal door between them. 
Another option is the
 Cabins at Disney's Fort Wilderness Resort. These also sleep 6. They have a full kitchen. There is one bedroom with a double bed and a bunk bed. In addition, there is a fold down "Murphy" style bed located in the living room. 
A final option is to choose one of the two-bedroom 
Deluxe Villas. These have a full kitchen, a living room, 2 bathrooms and more. 
Please let me know if I can help you further. I always travel with at least 6 people and so I'm very familiar with all of these options. 
Wishing you a magical vacation, 
Kaylene
