I hope you never need to use it but it’s nice to know it’s there if you need it.
I have been there with my husband and they are very nice. They take great care of you and make sure you are ok.
Disney doesn’t want you to be sick and not enjoy your time in the parks.
If more serious things happen their are urgent care centers not far from the parks. Also, their is Celebration Hospital nearby. It is a nice hospital (sadly was there with husband once).
I hope you never need these but I think you will feel better knowing they are nearby if needed.
Be safe and enjoy!!
