Gotta disagree with you again. Those are perfect for a toddler at the zoo. Basically replaces a wagon. Neither one belongs at WDW though.
A toddler, two teenaged cheerleaders, their Mothers and a Grandmother (each one more scantily clad and heavily made-up than the one before, and all wearing Summit cheerleader/spectator lanyards) board the monorail, the first mother pushing one of those fabric wagons with a stroller handle, which is loaded to overflowing with their handbags, makeup bag, snacks, clothing, merchandise, water bottles, spray fans, etc. The mother proceeds to have a loud, protracted phone conversation with someone [presumably her husband], demanding that he follow them to the Magic Kingdom immediately because, "we, like, left the umbrella stroller in the room, and where is our daughter [looking at the toddler] supposed to sit without it!??!" She says this while distractedly rearranging the overflow of various bags, totes and water bottles in the giant stroller in her hands.
Apparently strollers aren't just for kids anymore.
