I was just at Blizzard Beach yesterday (15AUG 2018) and one of these slides was closed. I wasn't thinking that there was supposed to be three slides there, but I saw a slide behind some bushes that didn't seem to exit anywhere. Turns out they closed and camouflaged them (in typical Disney fashion) pretty well. Anyone know when and why the slide was closed? I know a refurb is coming this winter.
