Hi, Kris! I am so sorry to hear of your daughter's injury. We are all sending her lots of pixie dust for a speedy recovery! This past summer, I injured my ankle just a few days prior to leaving for our trip to Walt Disney World Resort. I discovered that while I have always found Cast Members at the parks to be super helpful, they really went out of their way to help me that week.
Walt Disney World Resort covers a HUGE area and it can be quite a daunting task to walk everywhere, even without an injury! You will definitely want to get a wheelchair for her at each park. I am not sure of her age, but you may want to
rent an ECV/scooter if you think she can use one appropriately. Just inside each theme park and at Disney Springs, you will see the stroller rental locations. At these spots, they also have wheelchairs and ECVs to rent. You will find that the attraction queues and entertainment venues are handicapped accessible, so Cast Members will allow the wheelchair through the lines and direct you where to park it.
Kris, one thing I would like to mention to you is that the supply of wheelchairs and ECVs is limited and sometimes they do run out. There are several reliable Orlando-area mobility product rental companies that would be happy to help you and your daughter. This past summer, I rented an ECV from Buena Vista Scooters, who also has a rental stand set up outside Disney's BoardWalk Inn. They deliver products to all Disney resorts and many surrounding hotels, so be sure to check with them. Since any mobility product you rent at the theme parks or Disney Springs would need to be returned that day before you leave, you may want to rent from an outside company so that you would have use of it outside of the parks for the duration of your visit.
Thank you so much for stopping by today, Kris. Please let us know if you have any other questions!
