Last year we were at AKL at this time and the resort guide (Times Guide) had the dates, times, and locations of the characters throughout the week. (Santa included as well.) We've been fortunate to travel Christmas week many, many times over the years and I found last year to be the most lacking/infrequent in resort character greetings (not just AKL, but across all deluxe resorts). I was a little disappointed, to be honest. However, one of the nights we were there, we chanced upon Mickey & Minnie dressed up in their holiday outfits (great photo opps!). The lines were super long, but worth it. I asked the Cast Members there about the character greetings, since they weren't on the Times Guide and the CMs mentioned that Mickey & Minnie were actually at Kidani Village for a private event, but happened to loop through the lobby to surprise guests. It was an awesome Christmas miracle! I love the little elements of magic here & there. It was nice to have a little spontaneity since I plan Christmas week Disney trips quite a bit more because of the crowds. I just love the holiday outfits. One of my favorite family photos is with Stitch dressed as Santa right next to the Kidani tree by the staircase leading down to Sanaa.
Have fun & happy holidays!
