We went on 2nd October as well. We got the tickets at the special AP price. We ended up leaving just before the parade as I was not feeling well and kids were tired (it was the last night of our 2 week trip so we were a bit over it). Was disappointed to miss the fireworks.
There were pro's and con's for me:
Pro's:
*Kids really enjoyed dressing up and doing the trick or treating (my husband loved dressing up too, and he made me dress up as well which I admit was fun).
*Lot of lollies - my 3 year old couldn't believe his eyes when people kept putting handfuls into his bag.
*Loved the atmosphere - e.g. mist on Rivers of America, ghostly singers on rafts, etc.
*Seeing villans/characters not usually out and Mickey etc in the Halloween costumes.
*Some of the other costumes were amazing. There was one family dressed as Victorian ghosts - mum, dad and 3 little girls - the mum and girls in identical dresses and wigs, with so much detail, lace, frills etc, in a silvery grey colour. I so wish I had a photo of them!
Con's:
*Was REALLY crowded - I couldn't believe how many people there were, considering it was early in the month and it was a ticketed event. So it didn't feel at all exclusive.
*Control of people without tickets wasn't very good, e.g. 45 minutes past the start of the party there were people without wristbands lining up for the meet and greets.
*Some meet and greet lines were massive, e.g. 1 hour to meet Jack Skellington and Sally (and Sally wasn't guaranteed as she doesn't stay the whole time) - so even though my eldest daughter was dressed as Sally we didn't wait.
*Heaps of people weren't in costume (even kids) which made it feel sometimes like a normal night in DL.
Don't know if I'd do it again - if we happened to be there at this time of year and the kids really wanted to we might, but I wouldn't go out of my way. I didn't enjoy it as much as the Halloween party 5 years ago (was held in DCA then, and was much less crowded).
