We'll be there Friday, November 2nd as well.
This will also be our first day of our trip though, as we'll be arriving early that afternoon, and our 3 year old son's very first trip to WDW. I'm not quite sure if he'll be up for wearing a costume with all the excitement of his first airplane flight and everything that is WDW, but we'll bring one in the event that he'll be up for it.
He may very well be one of the very few without a costume or he'll be one of the very many dressed as Buzz Lightyear.
I'm very much looking forward to the trip in general (DUH), but particularly Mickey's Not So Scary Halloween Party, as this will be our first. I can't wait to see what all the hype is about and I definitely can't wait to see the look on my son's face.
