Do all Kids dress up for MNSSHP?

[dreams4disney]

We are still not sure if we are going to go to MNSSHP during our trip. We will Fly down and not have much room for extra's but I do have costumes. Just not sure what to do. If we did do it I wouldn't want my children to be out of place with out costumes.
Thanks!

Kids do dress up for MNSSHP (It's Halloween after all). A lot of adults dress up too. The first few parties in October are not as "dressed up" as the ones getting closer to Halloween. Your kids would not be "out of place" not having a costume as there is a fair mix of those that do and those that don't, but they may be a little upset that they don't have theirs. And don't forget ALOT of adults dress up too
