I'm amazed to see that Lucas really didn't have anything planned out in regards to the location of the carbon freezing chamber. To me, it makes no sense that the chamber would be located in the vane. You mean to tell me that Vader, all the stormtroopers, and the prisoners all took a trip up there to test the carbon freeze? I don't see any way that it makes sense to put that room up there. I had always assumed that it was located somewhere in the main city itself. But after following this thread, it does seem that Lucas did not actually map this out in the slightest. The problems with the room Leia and Han are in earlier is another great example of how there is no continuity at all. Doors lead to nowhere, and hallways that should be there don't even exist. I don't know how much of this can actually be fixed - I'm afraid there's a point where we're going to have to accept that the layout of Cloud City just doesn't make sense. Of course, we can always hope that Ady will pull something off with his magic!

At any rate, it's great to see those with a good grasp of these issues using their skills to illustrate them.

Perhaps Luke rode on a transit system for 15 minutes before reaching the carbon chamber, although the way the movie cuts, makes it look like he got there right after the previous cut.
