We saw the Mickeys' Twas the Night Before Christmas Show last night, it is in the Galazy hteatre in Tomorrowland, it is AWESOME! There are also the others, Osborne Lights, Candelight Processional, Holidays around the Worls....most of the Streetmosphere acts have holiday shows (saw the Beatniks yesterday) that are great....If you are wondering about anything specific I am sure I can help
Actually at the top of this thread is a link HOLIDAY HIGHLIGHTS AROUND WALT DISNEY WORLD. If you click on that it will give you listing of what's going on at each park, resort and DTD.
