The rides I miss the most are:
DT...with it's proper theming
Orient Express at Worlds of Fun. I loved the interlocking loops. It was a neat Arrow.
The submarine ride at Disney World. It was really cool as a kid.
I'm also going to miss the old Space Mountain. I know they are in the middle to totally re-building the Disneyland one. I have never been on that one, but I know it was a bit different from the World one because it sat two to a row.
I know they are going to re-do the Disney World one soon too. They have let the themeing get very outdated. I love the grey plastic balls they have way down on the floor as you enter the queue for the ride. It's a great ride in my opinion.
I will miss the quick hairpin turns of the classic Space Mountain.
