Space Mountain is amazing! Why would anyone want to change it? It's my favourite ride in WDW, and in my opinion alot better than the DL version. Everyone who complains of the 'turbulence' is clearly too old to be riding rollercoasters, and anyway its all part of the ride experience. Look what happened to the Alien ride when they refurbished that. No amount of publicity will make me go on that 'ride', it doesn't have anything on the old version. It would be a shame if they changed Space Mountain, because I think it's perfect just the way it is.
