You could go with connecting rooms at one of the values or moderates. A two bedroom villa at BayLake Towers, Beach Club, Boardwalk, Wilderness Lodge, Animal Kingdom Lodge, Old Key West, or Saratoga Springs would be the ideal option. You would have a king size bed in the master with a 2 room bathroom (one has a jacuzzi tub, vanity, large closet, the other has a walk-in shower, toilet, and sink), the second bedroom would have a queen bed and some have a double sleeper while others have another queen bed (OKW is one), you would have a living area with a double sleeper, full kitchen for quick breakfast, snacks, and drinks, and best of all a washer/dryer so you don't have to pack as much. You can rent through Disney or go to the DVC boards and look into renting points from a member - would be cheaper than going through Disney. We love the Boardwalk Villas. We have also stayed at the Old Key West villas years ago. With a large family the extra space is really nice.
