Hello Maria and thank you for bringing such an important question to the Disney Parks Moms Panel.
I can totally empathise with your query as I have a close family relative who suffers from Crohns Disease and I know that they would also find it quite uncomfortable to wait in-line for lengthy periods of time.
There are many
Services for Guests with Disabilities at Walt Disney World Resort and I'm happy to share with you information about
Disability Access Service (DAS) which can help disabled Guests who are unable to wait in a conventional queue environment.
The DAS provides Guests with a
virtual wait time which I think may be suitable for your darling daughter's particular needs. Guests may apply in person for a DAS from any
Disney Theme Park Guest Relations.
In addition, it may be helpful for you to know that it's easy to navigate to the nearest Rest Room with the help of the
My Disney Experience Mobile app; all you need to do is follow the arrows!
If I can help sprinkle any extra pixie dust onto your upcoming magical trip to Walt Disney World Resort please do pop back to ask me another question.
Have a great Disney day.
