There are plenty of kids there and it’s safe, it’s Disney. However I look at it like this, will having the kids with you impact your ability to fully partake in the festivities? It’s busier than most any other night. They do move traffic through the park well and I find it feels less crowded than on a weekend where they don’t have extra steps in place for crowds. It’s loud. Very loud. If you are going to worry about them all night and not enjoy yourself then if probably skip it.Just watched a stream of last year. Do you think it’s too adult for a 9 year old and 5 year old? I saw some strollers / little ones, but it seemed to thin out as the night wore on. We’d probably bring a double stroller in case my kids need to fall asleep, even though my soon to be 9 year old outgrew it several years ago and I’m probably way over the weight limit.
