Joan,
Thanks for your question to planDisney!
I just did a search for those dates, and I was able to find two resorts that definitely have rooms available during your stay. Both
Disney's Coronado Springs Resort and
Disney's Saratoga Springs Resort & Spa have rooms available at this time for the duration of your stay, though for the latter I only saw a 2-bedroom villa, so it may not match your needs.
Coronado Springs has long been a favorite resort hotel of mine. Since they added the new Gran Destino tower, I have grown to like it even more. It offers far more amenities and spaces than most moderate resort hotels, including what I consider to be some of the best lounges on property. In particular I love the
Barcelona Lounge right off of the lobby and the
Dahlia Lounge located at the top of the tower with its amazing views. I am sure this resort is accordingly turbo-charged with extra features since it is designed to support conventions, but regardless it has so much to offer that it makes my stays there far more comfortable.
While all of your transportation to parks and other destinations is via bus, I don't think it is such a big issue when you consider how centrally located it is on the overall Walt Disney World property. It is just a stone's throw away from
EPCOT,
Disney's Animal Kingdom Theme Park, and
Disney's Hollywood Studios.
If you think you will visit, I recommend you book soon, as it does look like Disney resort hotels are filling up at that time. Also be confident in knowing that at Coronado Springs you will find a more elevated hotel experience than most resort hotels in the area.
Have a Magical Vacation!
