Yea, I was surprised when we were told it'd still go outside. I'm all for it, but I was shocked.
That's why this will take less time to build, btw. The scenes that are there will be great, but this is still going to be a coaster. It will be more Big Thunder Mountain* than Gringotts
*Not in terms of thrill, IDK how thrilling it will be, just in terms of what people should be expecting from its coaster-to-scene ratio
