Well, an adventure without fold-out maps is certainly more runnable than it would be without maps AND an adventure.Is KotS really runnable without the fold-out maps, or at least some depiction of them? As I recall, the main adventure book has some close-ups showing monster starting locations, but it's gonna be hard and frustrating for a newbie to run the very first encounter without a map showing the whole encounter area.

I think the maps are nice, but I don't think they're essential. The DM was already responsible for drawing out most of the maps in KotS, and this is just a few more. Not a big deal.
