Thanks for your question Lynnette. The regular rooms at the Value Resorts accommodate a maximum four people, which is in accordance with fire codes. The All Star Music resort has recently added family suites, which might better suit your family as they are two room suites with a master bedroom (queen bed) and family room, which sleeps four on various pull-outs. They have a small kitchenette and two full bathrooms. I had a chance to view these in December and they're a great option for a larger family.
If you can take advantage of some of the great specials that Disney is offering like the
Buy 4 Get 3 Free deal, you might wish to consider a moderate resort. The Wilderness Cabins are centrally located, spacious (500 square feet), sleep six and have a full kitchen and a barbeque on your own private patio, providing an economical alternative to eating out. The Port Orleans Riverside resort is also a moderate resort, and the Alligator Bayoo section offers a pull out trundle bed one of your children might enjoy.
Best of luck in your planning!
