Hi, Elizabeth! Pricing information (while always subject to change) can be found at
www.disneyworld.com. But, so you do not have to search, here is what you are looking for!
Information/pricing for Stroller Rental: Click
HERE! To see a photo of the strollers, cut and paste this into your browser: http://www.magicalkingdoms.com/wdw/kids/strollers.html I know it is kind of hard to see, but they are made out of a sturdy plastic with a fabric hood. I always brought a blanket to put on the seat to make it more comfy for my little mouseketeers! These are not the prettiest strollers, but they are so easy to push, I love them!
