I'm beginning to worry a little too with all these negative reports. These hard ticketed events should be an enjoyable experience. You're paying extra to enjoy a less crowded park.
We attended
MNSSHP in mid October of 2013 and was shocked to see the crazy crowds. Long lines for ToT, M&G and still at least 3 people deep for the 2nd parade.
The only thing i had to compare to was the Pirate and Princesses party we attended years ago. That was so enjoyable. I know it's probably because it's not as popular but that was all i could compare it too.
we are attempting another party on Tuesday October 20th and if we run into a mess with crowds this will certainly be our last.
It's shame that all Disney cares about is the bottom dollar. It's getting very discouraging.

Hopefully The parties will be handled a little better seeing the chaos with the 1st party.
i'll plan for the worst and hope for the best
