It would be interesting, though, if the only planning tool people had was the official website. I do think it's fair to say that the fan sites have helped a lot of people over the years have more successful vacations, because historically, the official website is not accurate enough, detailed enough, or sometimes even functional these days (errors or loading a blank white page). The DIS is a constant stream of FP+/MB questions these day, I'm guessing in part because they either know not to check Disney's website, or couldn't find the answer there. WDW is getting better in terms of having menus, and all the times, but there are still things I try to find on the official site, and then go run off to AllEarsnet or somewhere else so I can find it faster. Fan sites are also more motivated to get info out quickly. Sometimes too quickly, but I would never be able to rely on an official site for up to date info about merchandise or food changes, just because "official" would never devote the resources to get every little thing. Nor sometimes would they want that info out there, like all the "testing" they are doing.
