As far as some place special for their kids... You're going to be in freakin' Disney World. Bam, special enough. If you're able to snag the character dining, great, if not, shouldn't kill the trip (especially because you can meet those characters elsewhere during the day). That's the hard part, there's more Katiebug's in the world now.
I don't have kids yet, but when I do, will I probably try and get those places, yes. If I succeed, I succeed, if I don't, I don't. It's nothing to lose sleep over. My family and I will be in Disney World and we'll make the best of it.
I know that my vacation experience is exactly that, mine. It's what I'm going to make of it. Rainy night at Epcot? Not a wash out for me.. put the ponchos on and let's go, etc...
If people would take 2 seconds, stand back and look at what they're trying to do (and see how miserable they're making themselves 6 months+ before they ever step foot in the parks) maybe Disney World could and would be a better place.
