I attended on the 16th. We were very lucky with the weather and had no parade or fireworks issues due to weather that evening. It was the only 1 of the 3 MNSSHP nights we were in town for that had no rain/thunderstorms.
My impression was the sold out night we attended had less attendance than my last pre-COVID MNSSHP party. I have absolutely no facts to support this, but I believe they are selling fewer tickets.
I did not know until afterwards that we were seeing the headless horseman's first ride since 2019....that was a cool fact and we always get chills seeing him ride.
I don't know if this is a new thing and we have missed it in the past, but POTC has some live actors. As one of my favorite nostalgic rides, that was a really cool twist.
I loved the fireworks. This is the first time we have viewed them from in front of the castle, and it was probably the highlight of the night. I like the Christmas projections, but the Halloween projections on the castle were on another level. I wish they ran them continuously throughout the night.
If you haven't been, stakeout a front row spot for the parade early. We have been many times and the prime viewing spots are always grabbed early. You really want front row and people will show up at the last minute and stand in front of you if you leave a gap.
It is also worth getting a good spot for the fireworks. There are things you will not see or not see well if you aren't in a good spot.
I was on the fence about MNSSHP after our last trip...it was too crowded and we did not feel we got a lot of value for our dollar. This was a non-park visit to Orlando, so we went well-rested and, with the lower crowd levels, we felt like it was money well spent.
