I suggest you really look at what days MNSSHP is being offered. We were scheduled to go to the party the 8th of this year, but my daughter came down with the stomach flu. I was really dissapointed, as I had pre-purchased my tickets. So, I started calling ticket services to see what could be done. They were really helpful and changed my tickets to the night of the 17th. While on the phone with them, they commented that someone was really going to benefit from our unfortunate situation, as MNSSHP had sold out for the 8th. With our cancelling our tickets for the evening, now four more others could go. I was really surprised the 8th had sold out! I didn't know that there were some other events going on that popped the interest in MNSSHP, like huge confrences, races, and being on a weekend, so locals were interested in attending. There were several people who did attend that night who were not thrilled with the event. They felt it was crowded. We seemed to have lucked out, because when we attended the 17th, it was excellent. No crowds to speak of, great fireworks, an amazing parade and fun trick-or-treating. It was well worth the rescheduling difficulties!!
So, my advice is to just check out what else is going on that might affect the night you chose. You will have a great time!!
