I'd either think that they'll have Kidzone close by January of 2018 or perhaps right after HHN27.
They'll have Fallon, Kong, Hulk, and various other things for guests to do. Along with Volcano Bay; considering if they do anything for the Holidays, I'm having to guess that they'll be fine if they want to close it during the time of the holidays. Atleast, that's what I would think.
