Terminally ill child visiting Disney - not sure how to help

Disclaimers: not asking for money, and the child's make a wish was already granted (in the form of a camper van so the family could make as many memories as possible on road trips as they don't have much money).

A terminally ill 6 year old is interested in visiting Disney and having some special experiences. As an unrelated neighbor, I met the child in passing and am now fundraising privately for the kid and helping to chip in for his trip. However, is there any way to contact Disney for some non monetary benefits? Like he doesn't have to wait in lines and can maybe get some special treatment (maybe like a chance to be part of a parade or something cool) and love (maybe some hugs from his favorite characters) during his trip?

If this isn't the right place to post, please let me know. Parents can connect any Disney representatives to the child's social workers, doctors, and hospital for immediate verification.
