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
