While there is no "official " HDDR kids menu, they do have alternatives available ( I believe they get it from the Trails End restuarant at Fort Wilderness)
They got my 2 year old son Mac and cheese with no problem.
Just ask your server.
We got a hot dog with french fries for our picky eater when we attended. We didn't even know it was an option. Our server offered to bring it to her when she noticed her not eating anything!!
