I believe you are correct about Hollywood's being the first batch. Honestly most casual guests don't even notice these problems, it's only the regulars who see them and care that much.
There's an amazing blog called
Passport to Dreams Old and New that did a great article on the levels of park fans, and she hits the nail on the head (though she's focused on Disney, it applies to all park fans). Casual guests generally think it's all wonderful and unless something is really "off" they hardly notice, it's only those of us who know all the ins and outs of the attractions and parks who nitpick.
