Of course it will make someone change their dates - I don't think WillowRain literally meant not one person will choose based on price. But I don't think most will. I know for us we have to choose vacation weeks based on school, when My DH is on call, when his partners already took off, when he can get 2 weekends in a row, activity schedules, etc...and then add on when we actually WANT to go. So with all of that going into when we go to Disney, I'm not going to also look at the Disney calendar to see when the tickets might be a little less expensive. That's just too much to take into consideration, and we're already spending so much that won't be our deciding factor. Maybe, just maybe, if 2 different times worked (like June or August, for example, to go right when school ends or right before it begins) I MIGHT take a peek at the price differences, but unless it was a drastic difference (and by that I mean something like a 50%-100% difference, not $20-$30 a ticket) I would not let that sway me on when I wanted to go.
