A friend of a friend is a cast member (not intimately related to the project, and as we know, they often don't know much anyway when it comes to details away from their position) and they said today that's it's closed as part of a park-wide push for queue improvement before Galaxy's Edge opens. Seems like if that's "all" they're doing then maybe it won't be down long. It could be that a project like that involves enough weather sensitive activities that an end date is hard to nail down. I'll be there in about a month and a half (during "fall") and am really hoping that it's opened up by then. After a cast member convinced my daughter that Harold the Yeti was just upset we were bobsledding through his mountain but otherwise he's a nice yeti she stopped bawling after her ride and later decided to try it again and has since decided that it's one of her favorites.
