First Aid at the Magic Kingdom is located towards the end of Main Street, U.S.A., on the Adventureland side If you have a medical emergency while at Walt Disney World, don’t panic. There is a First Aid station in each theme park and water park, and all Cast Members know what to do if there is an emergency. If you need to be treated, Disney will arrange transportation, if necessary, to a local Urgent Care facility (there are several in the area) or a local hospital. The closest hospital is AdventHealth Celebration. They saved my husband’s life a few years ago, so I recommend them.
