Don't take this the wrong way, but, I agree they are not living in a vacuum which is why most would decide for themselves what they like or don't like. You don't find that out by not seeing what is available to them. Anyone that reads a site like this one and thinks that they have reached a fact based location are not running on all cylinders.
Because we might think that DHS has nothing of interest does not mean, even slightly, that others see it that way. I have been more times then I can count and I still enjoy it. I will admit that I either use Park Hoppers or plan the day to be doing something else for part of it. I have never felt that, either way, I wasn't getting what I wanted out of my vacation. I, however, based on my experience, know what things I want to do again and what I can skip without concern. I didn't make that decision until I had experienced everything at least once. Because of that it makes me cringe when I read post where people adamantly tell others that they should not bother with an attraction because it sucks, is overrated or any of the multitude of reasons (don't like the color of the building) (dated) that are spewed out like it should matter to a first timer. In my opinion anyone that misses out on something that they might have liked because some one with a different set of tastes tells them not too, deserves to be taken. My motto... believe nothing that you read or hear and only half of what you see. Life is much more fun that way.
