The internet has phased most travel books out of relevance - which is why you now see the makers of the Unoffical guide hawking their online "customized" touring plans for $20 bucks a whack.
I bought the Unoffical Guide for years annually just to keep updated (say, from 90-99), but this year I bought it again for the first time in several. It's not much different. More pages doesn't mean better - I feel like they tack on to sections as opposed to truly updating them. I mean, Disney-MGM and Universal have been around for fifteen years, yet they are still lumped together in one section (though mysteriously, AK gets it's own).
It's little (big?) things like that that make me feel like they are slipping over there. The thing just needs a massive overhaul - I understand it's not geared toward repeat readers, but the foundation is getting very creaky. I also don't care for the endless relisting of the same data in a different format - I'd much prefer a single dining section with considered reviews of dining establishments broken up by location instead of three different lists listing them in different ways with relatively meaningless "star" ratings.
It's still the best book out there for WDW, but if you have internet access, between here, AllEars, and a few other sources, you can get just as much information as you need to make a magical visit, as with any travel destination in the Internet age. I have a hard time reccomending Unoffical Guide to many people these days, as I usualy send them to Birnbaum's which they find more visually stimulating if not critically superior.
Most people aren't prepared to wade through 800+ pages, and I can't reccomend it for a Disney-newbie, especially when I personally feel the layout has been suffering for quite some time. The thing could use a major editorial overhaul - it could be the best guide out there, Internet or not, if they shave off the excess and reorganized it from the ground up.
Just my opinion...
