We were at DL in February and I have to say they were super accomodating for the GF/CF diet that my daughters are on.
Storytellers Cafe at GCV was amazing. They did GF pancakes and pizza. The wait was not bad at all. At Goofy's Kitchen at the DL hotel the chef himself brought us GF brownies and cookies for dessert
We were able to get GF rolls inside CA.
I actually thought they were more attentive than WDW, even with not knowing in advance.
