If I had to choose, hands down,
MNSSHP. Matter of fact that's what we are choosing this year. We're only doing one.
MNSSHP:
You get to dress up in costume (but really, it's for the kids

)
You get candy candy and more candy
Halloween parade
Hallow Wishes
Characters in Halloween Costumes
Park is open late, and there's hardly anyone there
MVMCP:
You get free cookies (how many cookies can you eat in one night, really)
You get free scalding hot, I might add, hot cocoa
It "snows" on Main Street
Christmas parade
Holiday Wishes
Characters in Christmas costumes
Park is open late, and there's hardly anyone there
So really, different themes for the most part. But I love the candy collecting and the dressing up. It's more fun for me and the kids.
