I feel like Matterhorn goes down for a few months every year at this point. Maybe it's because it was the first steel roller coasters ever made and the track is so old. I would imagine there's a lot of required upkeep and maintenance since it's not like they can just go in and replace the track with new. I would imagine some queue improvement, too, as single rider and maxpass were sharing part of a line for a while, which didn't feel very organized. But, queue improvement doesn't take that many months. There's got to be a little more to it than that.
