We will be there that weekend also (Jan. 14-21). On Sunday we are doing the Extra Magic Hour - if they don't change it - at MK. Then lunch at Cinderella's. After that we are heading back to AKL. The kids (9 & 10) will go to Simba's Club and DH and I will just enjoy our balcony, with fast food from Mara. We will stay out of the parks as they will be crowded.
On Monday - we are not doing EMH, but will be heading over to Animal Kingdom later to see the parade - then heading over to Epcot for an Illumination cruise.
Trying to get the Illumination cruise on MLK day will be difficult, but I have my fingers crossed! We'll probably have dinner on the Boardwalk.
By Tuesday, the crowds will be gone and, although the park hours will be shortened, you will get a ton of things done.
