Not every situation is the same, and more people need to keep in mind that they don't know the whole story before they make snap judgements.
This is my thought exactly!

Everytime we've went, we've rented a stroller for our now 9 YO. Due to health problems, He simply doesn't have the stamina to walk all over WDW for 7 days.
He'll be 10 next trip..and we'll be getting one when he gets tired.
If people look and judge..I never know it, I'm too busy having a good time to notice!
