I read and re-read your intial post, and it hit me as "I don't like the restaurant situation, and since the parks are overpriced mediocrity, this just adds to it". It's not that I meant to single you out, or that one post was so terrible, it was more of a straw that broke the camel's back. And I honestly feel that if some of the people in here feel the way it seem they do about the Disney parks, then they honestly shouldn't go anymore. If you're not one of those, then I am sorry.
Let's say I work for a division in a company that is responsible for dreaming, designing and building something wonderful. Every now and then, I pop into places to see what people think, especially when we're rolling out some new products. When I get there, I mostly see one of four things: there are people who love it with all their heart, people who love/like it and have some well intended criticism, people who nit-pick the crap out of it because it doesn't meet some preconceived utopian ideal they have in their head from a trip 14 years ago, and people who hate it just because they hate. Now throw in a dash of people slamming this wonderful thing you try to make, becuase the other people in the company that you give it to in hopes of generations of use, don't bother keeping it up. Do you know how frustrating that would be, to pour years of your life into something unique and amazing, with all these tiny details, only to watch it die slowly out of neglect?
Of course, this is all hypothetical, but if you read an hour of how your little widget is just over-priced mediocrity (even if that wasn't the true meaning of the statement), could you see how it might hit a nerve? Not that it excuse me, it's just my reasoning for it.
By the way, the trick about dining reservations (my wife always makes them) is that you can book 180 days, or whatever they do now, from the beginning of your stay. You can usually get most places you want toward the end of your vacation, since you're actually booking out 184 days or so. But that all falls to another part of the company, so I have no control over that.
