Why don't you try looking at garage/yard sales? You can find practically new items if you look for it. Or you could look in your local ads for people selling them. Strollers are also nice to be able to throw in some other items you want with you in the parks, like water, or little snack items for kids. Best of luck finding what you are looking for. Have a great time at Disney.
