Celebrating holidays at Disney is so much fun, as the parks really do come to life in a whole new way. Magic Kingdom in particular offers two big celebrations — Mickey's Not-So-Scary Halloween Party and Mickey's Very Merry Christmas Party — both featuring special entertainment and effects (trick-or-treating for Halloween and "snow" for Christmas, along with a themed parade and fireworks show). Since the parks close to those who don't have tickets during these events and there's so much going on for those who do, guests can also typically benefit from shorter or even no wait times for rides.
