Checking luggage at stroller services in the park

I was just watching the Mouselets Instagram stories, and I heard an interesting fact. One of the mouselets heard that you can leave luggage at the stroller services in Epcot. She wanted to visit the park and then head directly to the airport afterwards it sounds like she had an annoying time getting through security with her bag as something went off, but it ended up working out pretty well. Stroller services charged her $10 per bag. I am thinking about doing this for my upcoming trip on my departure day, so that I can maximize per time. Has anybody done this before or heard of any other success stories?
