I am planning on going in October (Halloween week) and have not purchased a ticket yet. If I decide to not buy a ticket or cannot buy a ticket, I will rethink my reservation at Contemporary because that is why I reserved this resort to be close to MK for Halloween.
I can see there not being a parade, fireworks, meet n' greets, or candy given out, so the party would be a moot point if that is what will be happening. They would not want in congregating or waiting in lines. Will just have to wait and see what Disney does.
