3 MNSSHP options - Reccomended party night?

[DisFox]

I have the option of attending the Halloween Party 3 nights of my September visit. 9/7 Labor Day, 9/11 a Friday night, or 9/13 a Sunday night.
Labor Day works best for my plans but looking for recommendations and opinions on least crowded.

Personally, I would go on Sunday. Labor Day and Friday you'll get more locals at the parks. Sunday most people work the next day so probably not as many locals.
