We just returned a few days ago from a trip to Disney World and Sea World. Our first day at Sea World was fantastic, but the second day, not so great.
Long story short, on our way out of the park, we checked with guest services. As we were describing the stroller, another couple (they were also in guest services because someone had taken their stroller) heard us and said they knew where our stroller was. Apparently, someone had taken their stroller and left ours in its place. The other stroller was a very expensive stroller, so I guess the person(s) ditched our cheaper model for a better one.
Anyway, we finally got our stroller back, minus our grandson's Disney fleece blanket and my LL Bean jacket.

Now I know it isn't a good idea to leave anything unattended in a stroller, but I seriously didn't think someone would steal a baby's blanket OR a stroller.

Unbelievable!
Anyone else ever have something go missing from the parks?
