I got the Expidition to castle ravenloft, and compared it to my isometric drawings of it when I was younger (copied from interior of module). I found that while there is no big sweeping map, there are enough large peices to put it together, and the maps were laid out in a tactical manner so as to minimalize flipping through the book. Large chunk maps that were associated with different events instead of a room by room encounter system. It was kinda refreshing, looking forward to testing it on Halloween.
