I don't think the merry go round or carousel are chocolate -- they're gingerbread! Each of the deluxe resorts has one somewhere. In the poly, it's down on the first level, and one year included a small Lilo and Stitch, at AKL it was near the entrance to Boma. I think I remember a video at Beach Club of the making of theirs. As you can see, one of our holiday events is a tour of the resorts and their houses, and we have our own competition, finding the hidden mickeys in the houses.
Have fun whatever you do. I also recommend the Storytellers at Epcot.
