Hello, Kimberly,
Heading to WDW with your 4 grandkids in December, how absolutely magical!
First, I thought it would help if you read more about
Special Diets at Walt Disney World to learn more about making requests for accommodations and counter service restaurants that will have available options for your granddaughter.
Next, if you visit www.disneyfoodblog.com and do a search for
gluten free, you'll find many articles about visiting WDW while avoiding gluten. It will also link you to many other helpful sites that have more information, including orlandoglutenfree.com. Similarly, www.glutenista.com is filled with lots of good information; just search for
Walt Disney World.
In researching, I found a conflict of answers regarding the rice crispy treats being gluten-free, so I would encourage you to check directly with a cast member to confirm the ingredients.
Finally, did you know there is a BabyCakes NYC located in Downtown Disney, which offers an entire bakery of both gluten-free and vegan treats? The treats are wonderfully delicious.
Wishing you a fantastic trip!
