We are trying to decide if we want to buy tickets for MNSSHP for our Sept. trip. The only thing holding me back from buying them is the question of the noise level. Our 11 year old is autistic. Although noises don't normally bother him, the last two times we were at MK, the nighttime parade (Spectromagic) was extremely loud and seemed a little overwhelming for him. The descriptions that people give are that there is music playing throughout the event. Is the music during the event very loud? How does it compare to normal disney music that is usually playing. Also, is the Boo to you Parade as loud as Spectromagic?
The parade may be a little loud though. Definitely no louder than the other parades, (but ALL of the parades are a little loud). I also find that Hallowishes is louder than the regular fireworks, so I'm not sure how he would react to that. In general though, I think MNSSHP is a much calmer experience than a regular day in the park.
