I think you should just go. Honestly, we feel it is a do not miss. We have attended the last 5 years and we wouldn't miss it.
You won't have any down time before going, so if the kids can handle being up until 1:00 a.m. (by the time you leave the park and get back to the resort for bed), I would go and enjoy yourself. As for bad weather, you are never guaranteed that won't happen. We have been there when it has poured the whole evening. We just put on our ponchos and keep going. We got our pictures taken right away so cosutmes could come off since we were wearing ponchos and no one could see them anyways.
Here's what
MNSSHP has to offer:
Hours 7:00 p.m. - 12:00 a.m.

This is the only time you will see any of the parks decorated for Halloween.
If you decide to go....have a great time!!
