Just wanted to add another vote for the UG. It really covers everything, in a very logical and unbiased way. I think it offers so much more than other guides to WDW: it has interesting reflections on its own methodology, the history of WDW, how restuarant food is evaluated, etc. These are interesting reading in their own right (but then, I'm a philosophy professor, so you can imagine what my definition of interesting reading is). I looked at the Passporter, and, to me, it serves a totally different function. Not nearly as much info, but has storage pockets. Well, I have pockets in my backpack, so I don't really see the point of buying a book with pockets. As for my itinerary, I print out a copy in a small font for each day, fold it up, put it in my front shorts pocket, and go! For me, personally, the UG vs. Passporter is a substance over style issue. I also own the Birnbaum's, mainly because it has color park maps that are identical to the WDW park maps. I find these maps easier to use than the UG black and white maps, although the latter has improved maps in the 2004 edition, IMHO. Good luck!
