I totally agree Earthwurm (excuse the missing umlaut!), exactly my own thoughts on the matter.
I think, if they make it long enough, it would make a lovely addition to DMP.
I don't know what it is about Monorails, but for some reason, they always invoke that essence of "Theme Park" in me. I always feel a park without one feels a bit naked, like something is missing.
The only one that doesn't so much, is Alton Towers believe it or not. Theirs plays a useful, functional role, but never enters the park. I most certainly appreciate Alton Towers monorail more than most, for precisely that reason I mentioned, but I enjoy the one at Chessie as it's on park where they belong. I'm not counting Squirrel Nutty either, it's hidden away for the large part, and feels like a ride not a monorail due it's self containment.
They definitely add another layer to a park. I just hope they think of it of more than just a ride, and actually make it interact with the environment around it.
