This is often a big deal for people going in September. We however have still never done it. The extra ticket cost and fact there's so much else to do have always kept us from doing it. We have seen the Hallowishes fireworks from the Poly though, and they are very nice.
The first party is September 2nd this year, so those of us going in September will have the chance to go if we want to. What are your plans? Is MNSSHP a key part of your trip?
