Hi Kathy,
I am happy to let you know that there are many accommodations at Walt Disney World that include a full kitchen. You might consider the Cabins at Disney's Fort Wilderness Resort. Each stand-alone cabin includes a full kitchen. You can also look at the Disney Vacation Club resorts. Even though Disney Vacation Club members typically book these using vacation points, some of the villas are available for booking through traditional payment methods such as a credit card. Any one-, two-, or three-bedroom villa includes a full kitchen. These resorts are Bay Lake Tower at Disney's Contemporary Resort, Disney's Animal Kingdom Villas - both Jambo House and Kidani Village, Disney's Beach Club Villas, Disney's BoardWalk Villas, Disney's Old Key West Resort, Disney's Saratoga Springs Resort & Spa, the Villas at Disney's Wilderness Lodge, and the Villas at Disney's Grand Floridian Resort & Spa.
Since the size and location of these accommodations vary, it is hard for me to give you an estimate on price. I suggest that you search for the resort you are interested in using the full name, and go to the official Disney site for that resort. For example, here is the official site for
Disney's Old Key West Resort. From there, choose "Room Rates," which should bring up a list of the different types of rooms. For each, you will see a link to "View Seasonal Pricing," which will give you a calendar and cost per night. Sometimes Disney will release special offers; however, these are not yet released for the fall. When you are ready to make your reservation, call 407-W-DISNEY (407-934-7639) to speak with a cast member to do so.
I would love to help you plan more Kathy; however, I am limited in the space that I have to answer. Please do write back if you have any further questions!
