It seems they are.I heard about it so I emailed Special Diets.Here's my post from another thread - I'm a gluten free vegan so I emailed Special Diets to see what I could receive in the candy exchange.They asked me for my dietary restictions and what date I would be attending.Then I got this reply - Dear Karen,
Thank you for inquiring about how Walt Disney Parks and Resorts handles special dietary requests.
We have sent your request and information regarding the Mickey's Not-So-Scary Halloween Party to this location so that they are able to best assist you. On the day of your party, please go to Guest Relations in Magic Kingdom Park, let them know of your special dietary request and present a photo ID so that they may provide you with alternate options for treats.
I have no idea what I will get,could be a bag full of bananas! Should be interesting....
