Hi Ady,
Believe it or not, the holidays will be here before you can say "supercalifragilisticexpialidocious"! I am glad to hear that you will be attending one of the most festive holiday events at Walt Disney World.
Mickey's Very Merry Christmas Party will fill you with the spirit of the season in so many ways.
I have viewed the Once Upon a Christmastime Parade in several locations, but my absolute favorite spot is on Main Street, USA, where it "snows". Keep in mind, though, this is probably the most popular viewing location, so staking your space would probably need to happen about an hour, if not more, prior to the parade time. My family has used this waiting time to enjoy our complimentary hot cocoa and cookies.
Have a jolly time planning and feel free to stop back by with more questions. We would love to help you with more tips and suggestions.
