I have never been and wasn't planning on having a plan for MNSSHP. We've planned our other days much more than usual due to FP+ and I'm hoping we really don't need to plan MNSSHP. But, if y'all think we should plan it, then we will! My kids don't have any characters that are must-sees so the plan was just to see one if the line wasn't crazy. We want to do some rides during it, treat-or-treating, parade and fireworks. (We have two full days at MK before, so we won't focus on the rides but they definitely want to do some). We're going on a Tuesday in Sept, so I'm guessing likely a less crowded party than most.
