I wish I could say it was smarts that caused me to have the stroller receipt it was luck. I happened to shove them in my pocket after we started rolling. I am guilty of using that back pocket on the stroller as a catch all.
With as much as this happens at WDW, don't you think that Disney could put a stop to it? After all, it costs them money. Someone got out of paying $31 for each park stroller swiped. I have no idea how many times it happens but lets just for example purposes say a dozen times a day (across all four parks), I'm sure it's higher. That comes to $2,604 per week and $135,408 per year. This is a substantial revenue loss that could be stopped relatively cheaply.
I guess they could make money if it is a personal stroller stolen as the family would then rent one.
