It will be down August 26-September 5 according to some cast members I overheard talking about their schedules! They were discussing when they should plan a vacation. Of course, this isn't quite official information, lol, but it seems logical. I guess we will see!
From another thread about the HM Halloween overlay installation -- looks like we finally have some unofficial and official news on the overlay dates.8/26 info & hours are up on the DL website and if you look under attractions it says HM goes down that day. It still isn’t showing up if you just click on the calendar date though.
