Don't worry! You'll love it - it's awesome, it's fun, it's Disney like you've never experienced it. I read all about it before I went the first time and was so excited. Then the actual reviews from that year started coming in and everyone was complaining about crowds, bad/less candy, etc. But you know what...I had nothing to compare it to, and I loved it...
Now don't get me wrong...I KNOW Disney is scaling things back, cutting corners, crowding more people in...so I'm not disagreeing with repeat partiers who notice the differences. Part of the reason for these boards is so we can note differences in our experiences, and I appreciate knowing what has changed, etc. I'd be annoyed (and I may well be when I return for my 2nd party next month) if I'd experienced something I liked last time and it wasn't available this time, or my merch fell apart, and I too am REALLY annoyed about the monorail situation...but overall it's a great, fun experience for the majority of people.
