This is probably unpopular, but something that might annoy me, if I were a parent with kids in strollers planning to go to Disney, is if Disney outlawed the stroller I had. Money is tight, and space in townhouses (where I live) is tighter. It would annoy me if the stroller that I used b/c it was my "best value" (best features for best price which fit my kids best) was now not allowed, so I had to now needlessly spend $x to rent one all week, or buy a 2nd stroller just for a trip (and then donate it afterwards b/c there'd be no room at my house). I'd especially be annoyed with 1 month notice for trips where Disney almost requires planning everything more than 1 month out.
So, we make fun of the parents and their overwrought angst, but deep down, they do have a sliver of a point...it probably makes it harder and more expensive for them to go to Disney now for no "good" apparent reason in their minds (b/c Disney could do a lot of other things to manage walkways, but decided to choose their "needs" to do so vs someone else's or Disney's own pocket)...
