Hi, Phillip! You're such a good friend to try and gather information for this mom and her daughter to try to go to Walt Disney World!
Unfortunately, there are no discounted passes available for those with disabilities. There are, however, often discounts for Florida residents! Right now, there is a Florida Residents Go Wild pass, which allows residents to purchase a three day pass for only $99. The pass must be purchased by May 21st and used by May 24th, but this is a great deal!
You can check back here occasionally, or visit the official
Disney World website to find notification of other discounts that this family may qualify for.
I hope they find a way to make a visit to Walt Disney World happen!
