I have no problem with Doom disappearing, largely because the ride is soooo short. I do like the queue though, but I generally use my Express since the line is usually long due to it's poor capacity. I've only experienced the queue twice though, since standby is generally too long of a wait. The plus is that the attraction has a very recognizable & iconic footprint and decent theming, and it's a nice thrill. But, a big minus is that the attractions' length is measured in seconds rather than minutes. And also, capacity sucks. Mainly though, I would like more bang for my buck.
